7.the minimum value in the data set, xmin;

8.the first quartile (25th percentile), Q1;

9.the median (50th percentile), Med;

10.the third quartile (75th percentile), Q3;

Your students may have trouble with conceptualizing the meaning of standard deviation. Tell them it is a measure of variability (dispersion) that is related to the average deviation or average distance from a data value to the mean.

Method of Teaching

Use the Blackline Master 2.1 and 2.2 to create an overhead for calculating the numerical descriptions of a one-variable data set. Go over in detail the statistics provided by the calculator. Next, use the Blackline Masters 2.3 and 2.4 to create worksheets for the students. Have the students enter and save the non-weighted and weighted data sets, and then compute the numerical descriptions. Use the topics For Discussion to supplement the worksheets.
