Create a frequency distribution table or graph for the following set of data using ranges of scores by 10 (i.e., frequency for 51– 60, 61–70, etc.):
77, 75, 78, 56, 90, 68, 65, 63, 73, 77, 74, 78, 72, 79, 82, 85, 88, 52, 96, 71
Does this distribution appear to be symmetrical or skewed in shape? Explain your answer.
