SPSS Homework 2. t-tests. For SPSS Homework 2, you have three major steps for each problem set: the spreadsheet, the t-test, and the APA write up. Make sure you complete each step for both problem sets.
Hint: you will use two different t-test analyses in this homework assignment; make sure to round the appropriate values in your write-up .
When completing the homework assignment, please copy and paste your SPSS output into Microsoft Word in order. That is, you should copy and paste the SPSS output for Question 1, then Question 2. Then, repeat the steps for the second data set in the homework assignment.
To help ensure that your assignment files are accepted in BlazeVIEW, submit your Microsoft Word file using the following naming convention: LastnameFirstnameHW2.docx (For example, John Doe would submit the file with the name: DoeJohnHW2.docx)
The assignment will be due by the date listed in the Course Schedule and will be assessed using the SPSS HW 2 rubric.
Grading Standard: 30 points

Steps to Complete for Each Problem Set
Step 1: SPSS spreadsheet
Put the data into SPSS (data view)
Variable view name the variables
label the variables
set the number of decimal places to match the data
set the measure correctly
Use the snipping tool to paste Variable View & Data View into Microsoft Word
Step 2: SPSS t-test
Run the appropriate t-test in SPSS, including all options used in the example linked in BlazeVIEW. For each problem set make sure to determine the correct t-test to run for each problem set. For each data set, use a two-tailed test (SPSS’s default) with a 0.05 alpha level.
Copy the entire output into Microsoft Word.
Step 3: APA write up
APA format t-test write up for the problem set, written in Microsoft Word. Problem Set 1
A health psychologist is interested in the relationship between time of year one is born during and number of siblings. He randomly samples 26 participants at a local grocery store asking them what time of year they were born during (JantoJune or JulytoDec).
The researcher recorded that 13 were born during the months of January to June and 13 were born during the months of July to December. He then asks each participant how many siblings not counting themselves each has in their family. Does time of year one is born relate to their number of siblings?
HINTS: You cannot enter the data exactly as it is shown here. You need to do something (involving a condition column and values) in order to set up the data for the correct t-test). Remember your data and output should look like the example in the video in BlazeVIEW. When you interpret the output make sure to choose correctly if it is a one-tailed or two-tailed test based on the scenario above. JantoJune: 4, 2, 6, 4, 3, 5, 6, 3, 4, 2, 5, 4, 3 JulytoDec: 0, 1, 1, 1, 0, 2, 2, 2, 1, 1, 1, 3, 3 Problem Set 2
A researcher is interested in the effects of pleasant taste on memory. Participants (n = 15) were given a list of 20 words that were positive valence (i.e., happy, joy, smile) words. Participants were instructed to study the list of words for 10 minutes to learn as many as they could. The participants then wrote down the words they could remember. The research recorded the percentage of words remembered. Then participants ate a dessert of their choice. Participants were given a different list of 20 words that were positive valence words. Participants were instructed to study the list of words for 10 minutes to learn as many as they could. The participants then wrote down the words they could remember. The research recorded the percentage of words remembered. Does eating a dessert of your choice before studying a list of positive words improve one’s memory for a word list?
