Smartphone adoption among American young adults has increased substantially and mobile access to the Internet is pervasive. Fifteen % of young adults who own a smartphone are “smartphone-dependent,” meaning that they do not have home broadband service and have limited options for going online other than their mobile device. (Data extracted from “U.S. Smartphone Use in 2015,” Pew Research Center, April 1, 2015.)

If a sample of American young adults is selected, you can calculate various probabilities. This is a typical binomial probability situation because the young adults are either smart-phone dependent or not. There two possible outcomes which are mutually exclusive and collectively exhausted and satisfy all other properties of the binomial distribution.

Create your own situation that could be modelled with a binomial probability
P(X = x | n, π )
Where:
n = number of observations (the sample)
π = probability of an event of interest
x = number of events of interest in the sample
1. Define x, n and π in your situation. Select a sample size, n, between 5-20. Select a probability between 0-1 (of course!). Select x that is ≤ n.
2. Use the Excel function binom.dist to calculate the probability or the workbook ( click to download Binomial.xlsx) to create a binomial table. Your binomial table needs to have all possible outcomes included (e.g. x = 0, 1, 2, … , n).
3. Copy/paste your binomial table into your post.
4. Explain in your own words and in the context of your situation, the answer to the question, “What is the probability of P(X = x | n, π )?

Insomnia has become an epidemic in the United States. Much research has been done in the development of new pharmaceuticals to aide those who suffer from insomnia. Alternatives to the pharmaceuticals are being sought by sufferers. A new relaxation technique has been tested to see if it is effective in treating the disorder. Sixty insomnia sufferers between the ages of 18 to 40 with no underlying health conditions volunteered to participate in a clinical trial. They were randomly assigned to either receive the relaxation treatment or a proven pharmaceutical treatment. Thirty were assigned to each group. The amount of time it took each of them to fall asleep was measured and recorded. The data is shown below. Use the appropriate t-test to determine if the relaxation treatment is more effective than the pharmaceutical treatment at a level of significance of 0.05.

Question 1: The following data set shows the amount of time consumers must wait on hold, in minutes, before talking to a customer service representative. Compute the mean and standard deviation by hand (or Excel). Insert your answers and calculations in a word document. Last, explain what the mean and standard deviation tell you about this data set.

Question 2: The distribution of the ages of a nation’s population has a strong influence on economic and social conditions. The following table shows the age distribution of U.S. residents in 1950 and the projected distribution in 2075, in millions of people.
Because the total population in 2075 is much larger than the 1950 population, comparing percent in each age group is clearer then comparing counts.
1. Make a table of the percent of the total population in each age group for both 1950 and 2075. Use Excel or complete the table by hand.
2. Create two histograms using Excel or by hand. Create one histogram for the 1950 data and one for the 2075 data. Note: the Y-axis should be the vertical scale in percent for both the 1950 and 2075 population data. Insert the histograms into a Word document and discuss the main features of each histogram and compare them.

Part A. SPSS Assignment
In this exercise, you are playing the role of a researcher that is testing new medication designed to improve cholesterol levels. When examining cholesterol in clinical settings, we look at two numbers: low-density lipoprotein (LDL) and high-density lipoprotein (HDL). You may have heard these called “good” (HDL) and “bad” (LDL) cholesterol. For LDL, lower numbers are better (below 100 is considered optimal). For HDL, 60 or higher is optimal.

In this experiment, you will be testing three different versions of the new medication. In data file “Activity 8.sav” you will find the following variables: group (0=control, 1=Drug A, 2=Drug B, 3=Drug C), LDL, and HDL (cholesterol numbers of participants after 12 weeks).

Using a MANOVA, try to ascertain which version of the drug (A, B or C) shows the most promise. Perform the following analyses and paste the SPSS output into your Word document.

1. Exploratory Data Analysis.
1. Perform exploratory data analysis on the relevant variables in the dataset. When possible, include appropriate graphs to help illustrate the dataset.
2. Compose a one to two paragraph write up of the data.
3. Create an APA style table that presents descriptive statistics for the sample.
2. Perform a MANOVA. Using the “Activity 8.sav” data set, perform a MANOVA. “Group” is your fixed factor and LDL and HDL are your dependent variables. Be sure to include simple contrasts to distinguish between the drugs (group variable). In the same analysis, include descriptive statistics and parameter estimates. Finally, be certain to inform SPSS that you want a post-hoc test to help you determine which drug works best.
1. Is there any statistically significant difference in how the drugs perform? If so, explain the effect. Use the post hoc tests as needed.
2. Write up the results using APA style and interpret them.
Part B. Reflection
Reflect on your experience throughout the course and how you will use your new statistical skill set in the dissertation phase of your degree program. Include a brief assessment of what you have learned. In 2-3 paragraphs, cover the following:
1. What were the three most important concepts you learned?
2. How will the material in this course help you in your dissertation work?
3. What would you like to have seen covered that wasn’t or what would you have liked more practice with?

What are the most common reasons you would select a non-parametric test over the parametric alternative?

Statistics Question
Paper , Order, or Assignment Requirements

Part A. Questions about non-parametric procedures
1. What are the most common reasons you would select a non-parametric test over the parametric alternative?
2. Discuss the issue of statistical power in non-parametric tests (as compared to their parametric counterparts). Which type tends to be more powerful? Why?
3. For each of the following parametric tests, identify the appropriate non-parametric counterpart:
1. Dependent t test
2. Independent samples t test
3. Repeated measures ANOVA (one-variable)
4. One-way ANOVA (independent)
5. Pearson Correlation
Part B. SPSS Assignment
In this part of the assignment you will perform the non-parametric version of the tests you used in Week 4. In each case, assume that you opted to use the non-parametric equivalent rather than the parametric test. Using the relevant data files from Assignment #4, complete the following tests and paste your results into a Word document:
1. The non-parametric version of the dependent t test (use the SPSS dataset from Assignment #4, Part A);
2. The non-parametric version of the independent t test (use the SPSS dataset created in Assignment #4, Part B); and,
3. The non-parametric version of the single factor ANOVA (use the SPSS dataset in Assignment #4, Part C).

Construct an appropriate chart/graph that displays the relevant information for these two variables.

Statistics Question
Paper , Order, or Assignment Requirements

Part A. Dependent t test
For this assignment, we are interested in finding out whether participation in a creative writing course results in increased scores of a creativity assessment. For this part of the activity, you will be using the data file “Activity 4a.sav”. In this file, “Participant” is the numeric student identifier, “CreativityPre” contains creativity pre-test scores, and “CreativityPost” contains creativity post-test scores. A total of 40 students completed the pre-test, took the creativity course, and then took the post-test.
1. Exploratory Data Analysis/Hypotheses
1. Perform exploratory data analysis on CreativityPre and CreativityPost. Using SPSS, calculate the mean and standard deviation of these two variables.
2. Construct an appropriate chart/graph that displays the relevant information for these two variables.
3. Write the null and alternative hypotheses used to test the question above (e.g., whether participation in the course affects writing scores).
2. Comparison of Means
1. Perform a dependent t test to assess your hypotheses above (note that many versions of SPSS use the term “paired samples t test” rather than “dependent t test”; the test itself is the same.
2. In APA style, write one or two paragraphs that describe the dataset, gives your hypothesis, and presents the results of the dependent sample t test.
Part B. Independent t test
We will start with the data file used in Part A (“Activity 4a.sav”). Suppose, however, you [the researcher] encountered a small problem during data collection: after the post-tests were collected, you realized that the post-test form did not ask for the students’ identification number. As such, it will be impossible to match pre-test scores to post-test scores. Rather than simply give up, you start thinking about the data you do have and try to determine whether you can salvage your project. In assessing the situation, you realize that you have 40 pre-test scores and 40 post-test scores, but no way to link them. While it will result in a weaker comparison, you determine that you are still able to compare pre-test vs. post-test scores; you will use a between-subjects design rather than a within-subjects design.
1. Create the data set.
1. Using the “Activity 4a.sav” file as a starting point, create a new dataset that you can use with the between subjects design. Hint: you will no longer need the variables CreativityPre and CreativityPost. Instead, you have only one variable for the score on the creativity test. A second (or grouping) variable will serve to indicate which test the student took.
2. Save this dataset as Activity 4b.sav and remember to submit the file.
2. Exploratory Data Analysis/Hypotheses.
1. Perform exploratory data analysis on the creativity variable in the new dataset,
Activity 4b.sav. Using SPSS, calculate the mean and standard deviation using the
grouping variable.
