2. Sum of squares

Suppose you are interested in the relationship between a person's age and the amount of community activism in which he or she is involved. You randomly select 14 people from each of three different age categories and ask each person to estimate the number of hours spent engaged in any type of community activism or volunteer activity during the past 30 days (Xi). You obtain the following data summary from your investigation:

Age Group

18-30

?Xi=71

?Xi2=369

31-50

?Xi=68

?Xi2=352

Over 50

?Xi=79

?Xi2=483

In the following questions you will practice using the formulas from the text to calculate the main components of an ANOVA.

According to the summary data table, the total sample size is N = ___choices are:42, 102, 03, 14 and the overall mean isX?= ____ choices are: 15.571, 5.190, 6.488, 2.595.

The three category means areX?1=___ choices are: 5.071, 5.190, 4.857, 5.643, X?2=___ choices are: 5.190, 4.857, 5.643, 5.071, and

X?3= ___ choices are: 5.643, 5.071, 5.190, 4.857.

Calculate the sum of squares total (SST), the sum of squares between (SSB), and the sum of squares within (SSW) this data set.

SST =___ choices are 18.17, 36.34, 72.68, 109.02.

SSB =___ choices are 9.24, 1.55, 4.62, 0.20.

SSW =___ choices are 72.48, 71.13, 68.06, 77.30.
