Please continue to remind yourself about the issue of rounding error and should develop a general classroom rule to round to a specific decimal point (i.e., 2 decimal points) for all calculations. Problem set 1: Use the following data to answer questions 1-5 (30 points): A researcher is interested in whether there is a significant difference between the mean age of marriage across three racial groups. Based on the data below, answer these questions. Race N Mean Black 309 24.56 White 776 27.32 Other 165 29.08 All Groups 1,250 26.87 1. Calculate the value of the between group sum of squares (SSB, 10 pts). age of Race Y bar for each group Total mean Group mean- Total mean Square of the difference The number Nk Square of the difference of cases difference Black 24.56 26.87 White 27.32 26.87 Other 29.08 26.87 Sum up 2. Calculate the degrees of freedom for the between group sum of squares. Then, use this quantity to calculate the mean square between (6 pts). Df=3-1=2 2611.8714/2=1305.937 3. If the F statistic calculated for these data is 24.32, what is the value of the mean square within (4 pts)? Page 1 of 5 1014 words x English (United States) APR 21 Focus (A) hulu W + 150%
