Mr. White wanted to find out if there was a difference in the 3^rd period science TCAP scores (n = 38) versus 5^th period science TCAP scores (n = 34). The data are provided to you in Excel sheet called TCAP scores.

a.Generate summary statistics table (central tendency and variability measures) for the three samples and briefly summarize what they say.(2 points)

b.Generate a graph of the means of the two groups. Clearly label your axes, and give your figure a title.(1 points)

c.Conduct a test of significance for the difference between the mean test scores, show the table, and interpret the results.(2 points)

( 77 84 97 48 ) These scores are 3rd period, but they do not have a 5th period score. If we do not know those scores, we will just go on with the information we do have and omit those last four scores. The first number in the data set is the 3rd period, and the second number is the 5th data period.
