In this learning activity you'll examine the terms associated with a grouped frequency distribution and follows the steps to construct a grouped frequency distribution using manual methods.

In this learning activity you'll explore normal distribution and enter values for the mean and the standard deviation of normally distributed data and observe the resulting changes in the shape of the normal curve.

Learners follow the steps required to construct an ungrouped frequency distribution using either manual methods or a spreadsheet.

In this learning activity you'll calculate the numeric value of an area when given the z scores.

In this learning activity you'll use the Empirical Rule to calculate the percentages of data between two data points.

In this learning activity you'll identify and calculate the area under the normal curve specified by given z-scores.
