Assignment 2: Discussion: Measures of Central Tendency

By Saturday, July 18, 2015, post your response to the prompt in the Discussion Area below. Your initial response should be 1-2 paragraphs. Through Wednesday, July 22, 2015, review and comment on at least two peersâ€™ responses.

 Discussion Question

Simply reporting measures of central tendency or measures of variability will not tell the whole story. Using the following information, what else does a psychologist need to know or think about when interpreting this information?

A school psychologist decided to separate some classes by gender to see if learning improved. She looked at student scores on the final exam and obtained the following information: Students in boy-girl classrooms obtained an average of 71.4 on their final exams with a standard deviation of 10.8 whereas students in single-gendered classrooms obtained an average of 75.9 on their final exams with a standard deviation of 8.2. She concludes that the single-gendered classrooms lead to better learning.

Assignment 3: Research Design Questions

Suppose you were going to create your own study to examine what course-delivery format (online, blended, or face-to-face) leads to the best performance in a psychological statistics class. In a paper identify the following for your study:

• What is your research question?
• What is your hypothesis (both null and alternate)?
• Is this a qualitative or quantitative design (based on type of variable collected) and why?
• Is this a descriptive, correlational or experimental design and why?
• What would be an example of a variable for this study that could be measured on a nominal scale? Ordinal scale? Interval scale? Ratio scale?
• Once you have collected your data, would you use inferential or descriptive statistics and why?
• Create a sample frequency distribution for one of the variables. Choose either a simple or grouped frequency distribution and explain your choice.
