***Please complete the question under the abovel inks 

the template will be included here into files and the rubric is attached here too. Part 1:
Your instructor will provide you with a scholarly article. The article will contain at least one graph and/or table. Please reach out to your instructor if you do not receive the article by Monday of Week 3.
Part 2: Title your paper: “Review of [Name of Article]” State the Author:
Summarize the article in one paragraph:
Post a screenshot of the article’s frequency table and/or graph. Example:
Frequency Distribution -OR- Graph
Answer the following questions about your table or graph. What type of data does the graph, chart, or table from your screenshot above display (Quantitative or Qualitative data)?
Explain how you came to that conclusion. What type of graph, table, or chart did you choose from your screenshot above display (bar graph, histogram, stem & leaf plot, etc.)?
What characteristics make it this type (you should bring in material that you learned in the course)?
Describe the data displayed in your graph, table, or chart from your screenshot above. What is the graph displaying in the context of the article? Draw a conclusion about the data from the graph, table, or chart from your screenshot above in the context of the article. Make an inference based on the data displayed. How else might this data have been displayed?
Pick two alternate graphs/charts/tables that could be used to display the same data as your selected chart/graph/table from your screenshot above. List the pros and cons of these alternative graphs. Explain how the graphs/charts/tables that you selected above (Part E) would be structured to display the data in the article.
Give the full APA reference of the article you are using for this lab. Be sure your name is on the Word document, save it, and then submit it under “Assignments” and “Week 3: Lab”.

PLEASE LET ME KNOW IF
YOU HAVE ANY QUESTIONS.

I send the file that has all the data for spss. . . I want statistical analysis with hypothesis checks to compare population subgroups against the 9 factors present. Eg. How did the men get to factor 1 or 2 etc. . . Generally the subgroups are: Gender, age, experience, school, rank. The pages are indicative, I imagine the tables will take up space. Finally, they should be accompanied by a small commentary. Excell has the 9 factors with titles Greek for better understanding. In sav the factors are called Factor1new etc

This is for someone who likes data analysis and has a good understanding of statistics. You do not need to write this Research Report from scratch as you will be building on from the previous assignment titiled “Results and Interpretation” docx. However, there are very specific details and guidelines you need to follow in the course module outline, feedback from the markers and my notes. You will need to look at the feedback given and create an abstract as well as detailed analysis of the report. The topic 4 is anxiety measured before and after an intervention in adolescents at a school. References no later than 2018
I received 55% for the analysis of Assignment 2, however, it was moderated and remarked, and I obtained 74%. As you will see in the feedback, the opinions differ tremendously. This is imperative to read through all of the notes as to improve. I need to obtain 70% and above in order to pass this module. I will link youtube videos and notes. Your help will be appreciated.

ANSWER THE FOLLOWING QUESTIONS:
It is suspected that among fraternal twins, the first-born
twin has a higher resting heart rate from ages 0-2 years. The Excel sheet
provided by your instructor contains resting heart rate data (in beats per
minute) 129 pairs of randomly selected fraternal twins, measured at age 1 year.
Answer the following, furnishing relevant calculations and explanations where
appropriate:
(1)  
a.     
Write two to three sentences discussing the most
appropriate type of experimental design and sampling strategy for this
experiment.
b.     
Suppose that the data set in this experiment was
not provided to you, how would you judge what sample size to collect?
(2)  
a.     
What type of inferential test would be
appropriate in this situation? Be sure to include valid statistical
justification and discuss both confidence interval estimation and hypothesis
testing in your response.
b.     
Discuss the appropriate confidence and
significance levels. How did you calculate these values?
(3)  
a.     
State the formal null and alternative for your
hypothesis test determined in part (2) using symbolic form. Make sure to use
correct notation.
b.     
State the formal null and alternative for your
hypothesis test in words.
(4)  
Using the Excel sample data, complete the
relevant hypothesis calculations.
a.     
Include an Excel screenshot showing the summary
statistics relevant to this hypothesis test.
b.     
Furnish an Excel screenshot from the master
template, clearly highlighting the test-statistic, p-value, and any other
information you deem relevant.
(5)  
Make a formal decision on the null hypothesis.
a.     
State your decision in formal statistical
language.
b.     
State your decision using language relevant to
the application discussed (resting heart rate difference between the twins).
(6)  
Using the Excel sample data, complete the
relevant confidence interval calculations.
a.     
Furnish an Excel screenshot clearly highlighting
the confidence level, lower limit, and upper limit, as well as any other
information you deem relevant.
b.     
Is zero in your confidence interval? Explain why
this is important to note.
(7)  
Discuss the implication of the confidence
interval.
a.     
Does the confidence interval suggest the same
decision on the null as (6)? Explain how you arrived at your answer in detail.
b.     
Discuss what the confidence interval tells us
about the difference between the twins’ heart rates at age 1 year.
(8)  
If the sample size were increased to n=1290, but
the pattern in the data continued, what would you expect to happen to the
decision on the null? Would your decision be likely to change? Explain in
detail.
(9)  
Finally, list at least three possible
confounding variables that may cause this experiment to be biased or
untrustworthy. How could you modify the experiment to control for these issues?

Part 1 in 150 words :
Having a large amount of data is often beneficial in terms of generalization (extending results from a sample to the corresponding population), but in its raw form, it is very difficult to draw conclusions from. Descriptive statistics provide summaries of the data, and help us make initial inferences that are as accurate as possible. They also form the building blocks for the analyses used to test hypotheses and answer research questions.
Measures of Central Tendency and Variability
For this discussion, you will look at each type of descriptive statistic, and reflect on their advantages and disadvantages. Develop a main response, in which you address the following:
* Identify which descriptive statistic is the most informative and the most useful.
* Explain why you selected it, highlighting its advantages over the others.

Probability is a concept that relates to everyday life, as well as to statistics. In everyday life, we use probability to evaluate choices, make decisions, and interpret outcomes. In statistics, probability is used in similar ways.
Finding Probability
For this discussion, begin by reflecting on your daily routines. Identify a recent situation in which you have used or applied probability to help you make a decision or evaluate something. Then develop a main response in which you address the following:
* Summarize the situation that involved probability.
* Explain how probability was relevant.
* Discuss how you applied probability.
* Evaluate the extent to which probability helped the overall situation.
