Using R, answer the following question. The accompanying data
set contains quiz scores for 12 students in a chemistry class: 18,
15, 5, 8, 15, 20, 2, 16, 10, 12, 20, 15.
Find a measure of central tendency that separates the data into
two groups such that each group consists of 50% of the scores above
and 50% of the scores below that measure.
Find a measure of central tendency that represents the average
of the 12 quiz scores.

Assume that Data Set C depicts scores for 30
individuals who participated in a two-way independent groups
design. Analyze the data using a two-way ANOVA and complete an
ANOVA table reporting the relevant DD, df, MS, and Fs. Make sure to
also report each of your critical values and indicate whether you
would reject each of your three null hypotheses (i.e., main effect
of A, main effect of B, interaction of A x B)
