Normal Distributions

Students investigate the area of squares and circles. In this geometry lesson, students calculate the area and probability of simple events. They work on a laptop using Safari.

Does standard deviation work for non-symmetrical distributions, and what does it mean? Through the use of examples, high schoolers determine the standard deviation of a variety of distributions and interpret its...

Being a statistician means never having to say you're certain! Learners develop two-way frequency tables and calculate conditional and independent probabilities. They understand probability as a method of making a prediction. 

When presented with categorical data, a two-way frequency table is a great way to summarize the information. Pupils organize categorical data using a two-way table, then use the tables to determine missing data and to calculate simple...

 The section of a larger General Certificate of Secondary Education math review requires pupils to summarize numerical data presented in a frequency table. Scholars determine the number of data points, the range, the mean, and the...

What did the math book say to the psychology book? I have a lot of problems. A helpful video covers how to calculate the margin of error with various standard deviation numbers. 

To recall or not to recall, that is the question. Using provided data, pupils calculate the percent of people that may fall ill on average. The scholars determine the standard deviation based upon the mean and the empirical rule,...

Deviation is normal in the world of statistics. Viewers first learn about the normal distribution curve in an informative video. They then watch as the narrator calculates standard deviation by hand and using spreadsheets.

A picture is worth a thousand words, and this is no exception! The introductory photo shows a group of classmates lined up in height categories; females and males are in different colors, and the shape of the curve they create is...

Does the size of the bin matter? The resource allows pupils to explore the relationship between the normal curve and histograms. Learners view histograms compared to a normal curve with a set standard deviation. Using the interactive,...
