Teaching Intuitive Statistics. II. Aiding the Estimation of Standard Deviations
Lovie, Patricia
International Journal of Mathematical Education in Science and Technology, 9, 2, 213-9, May 78
In this study, the subjects were found to produce better estimates of standard deviations by using a "range rule" than by a direct estimation procedure, particularly when the sample variances were small. No differences were found in the subjects' performance in making direct estimates of standard deviations and variances. (Author/MN)
