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

Learners read about the different uses of the word "data." They will test themselves on examples of data that is singular, plural, qualitative, quantitative, nominal, ordinal, interval, rational, discrete, or continuous.

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.

In this learning activity you'll create a stem and leaf plot.

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

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

Learners follow steps to establish class boundaries and tally the data using a spreadsheet.

In this interactive object, learners read how to arrange numerical data manually by using ascending or descending order. They also practice arranging the data using a spreadsheet.

In this interactive object, students read about organizing data in a tabular form. A brief quiz completes the activity. This is the first in a series of six learning objects.

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

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.

Students follow step-by-step directions for entering data into a spreadsheet and reporting the results.

Learners follow steps to establish the lower and upper limits in a spreadsheet.

Students follow steps to transfer data from a list to a histogram.

In this interactive object, learners read the definitions of terms associated with the construction of a grouped frequency distribution. A brief quiz completes the activity.

Students examine an Excel spreadsheet to determine range, class, and width.
