Q: A researcher tested the reading ability of two groups of primary care patients. The scores on the test range from 1 to 9 with 9 indicating a high degree of reading ability and 1 very limited reading ability. The researcher is interested in knowing the average level of reading ability for each group separately and for the sample as a whole. Calculate these indices using appropriate statistics, provide a rationale for the ones you chose to use and provide an interpretation of the results.
Group 1: 4, 8, 6, 6, 2, 1, 7, 3, 4, 3
Group 2: 5, 8, 7, 2, 4, 5, 2, 9.
