Pretend you are researcher interested in assessing in studying the texting habits of college students. You ask a random sample of 60 students to tell you how many texts per day they send. Make up a data set that contains 60 numbers representing the number of texts per day each student reports sending. Then make a histogram for the raw scores, convert the scores into Z scores using SPSS, make a histogram of the Z scores.

SPSS Analyses Instructions:

1. Find the mean and standard deviation for the raw scores
2. Make a histogram of the raw scores
3. Transform the raw scores into Z scores following the instructions on p. 106 in your textbook
4. Find the mean and standard deviation for the Z scores
5. Make a histogram of the Z scores

Make an in depth summary of your SPSS analyses from the perspective of being the researcher yourself and include the following:

• Explanation of what the study was about - as if you are the researcher conducting the study in the hypothetical scenario above, but you must use your own words to explain things.
• Explanation of what the numbers in the data set represent
• Report of the mean and standard deviation for the raw scores
• Report of the mean and standard deviation for the Z scores
• Description of any notable characteristics of the data that you can see by looking at the histogram for the raw scores and the histogram for the Z scores. In particular, you should describe the shape of the distributions, any skewness or asymmetry, any outliers, or other unusual data. Are the distributions unimodal, bimodal, multimodal, or is there no mode?
