A psychology researcher is comparing the results of a social-anxiety scale across four different participant groups. All groups have an average (mean) score of 20. Based on the dispersion of the scores provided, arrange the groups in order from the lowest standard deviation (least variability) to the highest standard deviation (most variability).

A researcher measures self-esteem scores for two samples of university students. Sample A has a mean of 30 with a standard deviation of 3, and Sample B has a mean of 30 with a standard deviation of 9. Based on these values, individual self-esteem scores in Sample B are, on average, closer to the mean than the scores in Sample A.
