Bar Graphs - Math Lesson Grade: 2 - 6 In this lesson, learn that a bar graph is a visual way to display and compare numerical data. 1:20 |
Histograms - Math Lesson Grade: 2 - 6 In this lesson, learn that a histogram is a type of bar graph that shows the frequency of data in various intervals. 1:35 |
Pictographs and Line Plots - Math Lesson Grade: 2 - 6 In this lesson, learn that a line plot is a graph that shows the shape of a data set by using x's above each value on a number line. Students also learn that a pictograph is a graph that shows data using picture symbols. 2:55 |
Line Graphs - Math Lesson Grade: 2 - 6 In this lesson, learn that a line graph is used to show change over time, and the points on a line graph are plotted like the points on a coordinate grid. A double line graph displays two sets of data on the same graph. 1:50 |
Statistics: Decisions Through Data: What Is Statistics? Grade: 5 - 12 Learn what statistics is. The lesson unravels the statistical arguments behind surveys, polls, experiments, and product claims. 12:25 |
Statistics: The Average Grade: 5 - 12 Introduction to descriptive statistics and central tendency. Ways to measure the average of a set: median, mean, mode. 12:35 |
Statistics: Sample vs. Population Mean Grade: 5 - 12 The difference between the mean of a sample and the mean of a population. 6:40 |
Statistics: Variance of a Population Grade: 5 - 12 Variance of a population. 12:25 |
Statistics: Sample Variance Grade: 5 - 12 Using the variance of a sample to estimate the variance of a population. 11:20 |
Statistics: Standard Deviation Grade: 5 - 12 Review of what we've learned. Introduction to the standard deviation. 13:05 |

Poisson Process, part 2 Grade: 8 - 12 More of the derivation of the Poisson Distribution. 12:40 |
Law of Large Numbers Grade: 8 - 12 Introduction to the law of large numbers. 9:00 |
Introduction to the Normal Distribution Grade: 8 - 12 Exploring the normal distribution. 2:25 |
Scatter Plots and Trends - Math Lesson Grade: 8 - 12 In this lesson, learn that a scatter plot is a graph in which the data is plotted as points on a coordinate grid. A 'best-fit line' can be drawn to determine the trend in the data. 2:45 |
