Without performing any calculations, determine which measure of central tendency best represents the graphed data. Choose the correct answer below. Frequency How Often Do You Change Jobs? 1250 1000- 750- 500- 250- 0- Every 1-3 years Every 4-5 years Every 6-10 years Stayed at one job >10 years OA. The mode is the best representation of the data. The distribution is uniform and there are no outliers. OB. The mean is the best representation of the data. The distribution is symmetric and there are no outliers. OC. The mode is the best representation of the data. The data are at the nominal level of measurement. O D. The median is the best representation of the data. The distribution is skewed left with several outliers. O E. The mean is the best representation of the data. The distribution is uniform and there are no outliers. OF. The median is the best representation of the data. The distribution is skewed right with several outliers.

The data represent the​ time, in​ minutes, spent reading a political blog in a day. Construct a frequency distribution using 5 classes. In the​ table, include the​ midpoints, relative​ frequencies, and cumulative frequencies.

The graph below is an ogive of scores on a math test. The vertical axis in an ogive is the cumulative relative frequency and can also be interpreted as a percentile. Use the graph to approximate the percentile rank of an individual whose test score is 45. 100- 90- 80- 70- 60- 50- 40- 30- 20- Percentile Ranks of Math Test Scores 10- 0- 0 10 20 30 40 50 60 70 80 90 100 Q N C C C
