mean, mode, standard deviation
range, standard deviation, variance
mean, median, and range
mean, median, and mode
Question 3 of 13

Question 4 of 13
Which measure of central tendency represents the value that occurs most frequently in a distribution?
Question 5 of 13
Which measure of central tendency represents the 50% percentile of a distribution?
Question 6 of 13
Which measure of central tendency represents the sum of all values divided by the total number of values in a distribution?
Question 7 of 13
Which measure of central tendency is most effected by extreme values?
Question 8 of 13
Which measure of central tendency is least effected by extreme values?
Question 9 of 13
Which measure of central tendency is used as an estimate for this same measure of central tendency in the population?
Question 10 of 13
Why is the mean so important in quantitative research?
It helps us summarize our sample data down to one value
It is used as an estimate of the population mean
The mean is the only measure of central tendency that is calculated using every value of the distribution
All of the above
