Bar Graphs  Math LessonGrade: 2  6 In this lesson, learn that a bar graph is a visual way to display and compare numerical data. 1:20 

Histograms  Math LessonGrade: 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 LessonGrade: 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 LessonGrade: 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 AverageGrade: 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 MeanGrade: 5  12 The difference between the mean of a sample and the mean of a population. 6:40 

Statistics: Variance of a PopulationGrade: 5  12 Variance of a population. 12:25 

Statistics: Sample VarianceGrade: 5  12 Using the variance of a sample to estimate the variance of a population 11:20 

Statistics: Standard DeviationGrade: 5  12 Review of what we've learned. Introduction to the standard deviation. 13:05

Poisson Process, part 2Grade: 8  12 More of the derivation of the Poisson Distribution. 12:40 

Law of Large NumbersGrade: 8  12 Introduction to the law of large numbers 9:00 

Introduction to the Normal DistributionGrade: 8  12 Exploring the normal distribution 2:25 

Scatter Plots and Trends  Math LessonGrade: 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 'bestfit line' can be drawn to determine the trend in the data. 2:45
