pt 1

Use the data file with the raw scores into SPSS, use SPSS to find the mean of the raw scores, and conduct a one-sample Z test.

SPSS Analyses:

• Find the mean IQ score for the entire sample of fifth-graders in SPSS

Hypothetical Scenario:

Pretend you are researcher interested in evaluating the IQ of a class of "gifted" fifth-graders to see whether their mean IQ is significantly higher than the mean IQ of the general population. You administer a standardized IQ test to the "gifted" fifth-grade class and the data are provided in "Raw Data-1.txt". Assume it is known that the IQ test you are using has a mean of 100 and a standard deviation of 15 when given to fifth-graders in general. It is also known that the test scores of fifth-graders in general are normally distributed.

pt 2

indepth summary of your 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. Don't just copy the paragraph I gave you, but make sure you are using the same basic scenario.
• Explanation of what the numbers in the raw data set represent
• Description of all of the procedures used to analyze the data
• Report of the outcome of your one sample Z test (report z-value, the p-value, and your decision (i.e., whether you decided to reject the null hypothesis or not), and your conclusion
