In data analysis, measures of central tendency are essential when it comes to the understanding of different attributes of the dataset. In most cases, it reveals the characteristics of the study participants or respondents, their mean, mode, the median, maximum and minimum numbers. The following tables indicate the descriptive statistics for the National Cancer Institute 2018.

Table 1:

American Indian / Alaska Native (includes Hispanic)
Measure of central tendency	Value
Mean	43.275
Median	43.85
Mode	N/A

Table 1

Asian / Pacific Islander (includes Hispanic)
Measure of central tendency	Value
Mean	38.5125
Median	38.9
Mode	36.6

Table 3

Table 3: Black (includes Hispanic)
Measure of central tendency	Value
Mean	70.06875
Median	71.4
Mode	N/A

Table 4

Table 3: Hispanic (any race)
Measure of central tendency	Value
Mean	31.49375
Median	32.1
Mode	34.1

Table 5

Table 3: Hispanic (any race)
Measure of central tendency	Value
Mean	62.725
Median	64.55
Mode	65.8

The tables above show the rate of cancer infection among the races as indicated. The measurements were made per 100, 000 persons. The black community showed the highest rate of cancer infection followed closely by whites. Hispanic race recorded the lowest rate of cancer infection. The data for analysis was recorded from the year 2000 to 2016, a period of 16 years. For the American Indians who participated in the research process, the highest rate of infection per 100,000 people was recorded as 51.7 while the lowest rate of infection was 32. The above information was recorded in the year 2004 (Bilimoria et al., 2018). For the Hispanics, blacks, and whites, the highest rates of infections were recorded as 35, 79, and 68.8 respectively.

Table 6: Measures of Variation

Ethnicity/Race	White (includes Hispanic)	Asian / Pacific Islander (includes Hispanic)		American Indian / Alaska Native (includes Hispanic)	Black (includes Hispanic)	Hispanic (any race)
Variance	26.162	5.679		27.719	45.429	8.3998
Standard Deviation	5.115	2.383		5.2646	6.740	2.8982
Maximum	68.8	41.8		51.723	79.00	35.00
Minimum	53.2	34		32.00	57.42	26.00
Range	15.6	7.8		19.7	21.6	9

From table 6, the highest variation rate was observed among the black participants. The black community had the highest rate of cancer infection with the highest variation recorded. The measurements were recorded for every 100,000 people. The variations were the representatives of the deviations from the means per 100,000 people.

Question Description
I need help with a Statistics question. All explanations and answers will be used to help me learn.

Please read the discussions and respond to them with reference

Discussion 1

Correlation is a statistical technique that is used to measure and describe the STRENGTH and DIRECTION of the relationship between two variables.

Correlation requires two scores from the SAME individuals. These scores are normally identified as X and Y. The pairs of scores can be listed in a table or presented in a scatterplot. Usually the two variables are observed, not manipulated.

The error in this correlation is that there needs to be more data to determine that there are no other factors involved that could cause the heart rate to increase besides just cigarettes.

Discuusion 2

When I look up the definition of linear correlation I find the following:
1. mutual relation of two or more things, parts, etc.

2. the act of correlating or the state of being correlated.

3. (in statistics) the degree to which two or more attributes or measurementson the same group of elements show a tendency to vary together.

So i believe we could stipulate that there could be a correlation between the cigarettes and the pulse rate but i think we would eed more data to say specifically that one influenced the other. I am sure that the pulse rate would go up with nicotene but is there other things involved. Did the person have caffeine recently? Is there outside stress? What meds are they on? Just some of the examples of things that also could be influencing the pulse rate.

Discussion 3

The assumption is that cigarettes alone are one variable that is causing the increased heart rate. There are many factors that can contribute to an elevated heart rate besides cigarette use, there are other attributing factors like caffeine, chocolate, AF, fight or flight syndrome to name a few. With statistics there needs to be an x and y for the comparison of the data. To make a null hypothesis without any data to back it up is in error. The study needs a theoretical framework to give it validity. Otherwise this is like politics where I can make any statement that supports a theory of mine but there is no data to back it up and therefore I will not have any validity with the next statement that I release to the press. That would be the beauty behind science and statistics that there is a study that has been validated with a study that shows our results that either prove the null hypothesis or cause the rejection and thereby a new study established.

Discussion 4

Correlation is used in statistical analysis to determine the type and extent of a relationship between two variables (Lecture 5, 2013). Although we may be able to see a correlation between two variables, we cannot make a conclusion without further evidence. The error occurs in the given example because correlation does not exactly imply causation. There could be many other variables affecting the pulse rate that are not listed. For example, the person could be super stressed, causing him/her to smoke more cigarettes and at the same time running around at a fast pace trying to complete tasks/errands. We would need to gather more information in order to directly correlate cigarettes to an increased pulse rate.

Discussion 5

As it states in our Week 5 lecture, correlation does not mean cause and effect. The error here is the assumption that pulse rate and amount of cigrettes are mutually exclusive. The error would be to ignore other factors that could increase the heart rate of the participants. What kind of stress do they have going on in their lives, what did they eat that day, how was their water intake that day. There are so many other variables that could cause one’s heart rate to increase. Could there be a correlation, sure, but there is no evidence that that is the main cause.

Discussion 6

The error in this conclusion is the lack of information provided. What was the study size? How many times was this tested? How many cigarrettes were smoked in a row to provide this conclusion, and was this a controlled study? Was caffeine ever drank while the user was smoking? More information is necessary in order to verify the validity of this study. For all we know based on the information provided, this could have been one person monitoring his heart rate while smoking, and because he had an elevated heart rate, he came to this conclusion.

You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes.

Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages.

Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor.

The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument.

ADDITIONAL INSTRUCTIONS FOR THE CLASS

Discussion Questions (DQ)

Initial responses to the DQ should address all components of the questions asked, include a minimum of one scholarly source, and be at least 250 words.
Successful responses are substantive (i.e., add something new to the discussion, engage others in the discussion, well-developed idea) and include at least one scholarly source.
One or two sentence responses, simple statements of agreement or “good post,” and responses that are off-topic will not count as substantive. Substantive responses should be at least 150 words.
I encourage you to incorporate the readings from the week (as applicable) into your responses.
Weekly Participation

Your initial responses to the mandatory DQ do not count toward participation and are graded separately.
In addition to the DQ responses, you must post at least one reply to peers (or me) on three separate days, for a total of three replies.
Participation posts do not require a scholarly source/citation (unless you cite someone else’s work).
Part of your weekly participation includes viewing the weekly announcement and attesting to watching it in the comments. These announcements are made to ensure you understand everything that is due during the week.
APA Format and Writing Quality

Familiarize yourself with APA format and practice using it correctly. It is used for most writing assignments for your degree. Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for APA paper templates, citation examples, tips, etc. Points will be deducted for poor use of APA format or absence of APA format (if required).
Cite all sources of information! When in doubt, cite the source. Paraphrasing also requires a citation.
I highly recommend using the APA Publication Manual, 6th edition.
Use of Direct Quotes

I discourage overutilization of direct quotes in DQs and assignments at the Masters’ level and deduct points accordingly.
As Masters’ level students, it is important that you be able to critically analyze and interpret information from journal articles and other resources. Simply restating someone else’s words does not demonstrate an understanding of the content or critical analysis of the content.
It is best to paraphrase content and cite your source.
LopesWrite Policy

For assignments that need to be submitted to LopesWrite, please be sure you have received your report and Similarity Index (SI) percentage BEFORE you do a “final submit” to me.
Once you have received your report, please review it. This report will show you grammatical, punctuation, and spelling errors that can easily be fixed. Take the extra few minutes to review instead of getting counted off for these mistakes.
Review your similarities. Did you forget to cite something? Did you not paraphrase well enough? Is your paper made up of someone else’s thoughts more than your own?
Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for tips on improving your paper and SI score.
Late Policy

The university’s policy on late assignments is 10% penalty PER DAY LATE. This also applies to late DQ replies.
Please communicate with me if you anticipate having to submit an assignment late. I am happy to be flexible, with advance notice. We may be able to work out an extension based on extenuating circumstances.
If you do not communicate with me before submitting an assignment late, the GCU late policy will be in effect.
I do not accept assignments that are two or more weeks late unless we have worked out an extension.
As per policy, no assignments are accepted after the last day of class. Any assignment submitted after midnight on the last day of class will not be accepted for grading.
Communication

Communication is so very important. There are multiple ways to communicate with me:
Questions to Instructor Forum: This is a great place to ask course content or assignment questions. If you have a question, there is a good chance one of your peers does as well. This is a public forum for the class.
Individual Forum: This is a private forum to ask me questions or send me messages. This will be checked at least once every 24 hours.
