Statistics

6 interactive Mathematics simulations on statistics.

Mathematics · Statistics Grouped frequency table and relative frequency chart A data sample (student height, weight, or daily self-study time) is grouped into classes of a chosen width. The frequency table n_i,... Ages 14–15
Mathematics · Statistics Data charts – bar, line, and pie from the same table A single data table (monthly temperatures, top students per class, quarterly revenue…) is drawn as a bar chart, a line graph, or a pie... Ages 12–13
Mathematics · Statistics Choosing chart types – misleading graphs The same dataset is drawn as a bar chart, grouped bar chart, line graph, and pie chart. Students switch chart types, drag the top of a... Ages 13–14
Mathematics · Statistics Variance, standard deviation, and IQR of grouped data Two samples with the same mean but different spread are grouped and plotted overlapping each other. Drag each sample's σ slider to watch... Ages 17–18
Mathematics · Statistics Mean, median and mode of grouped data Generate a sample of test scores out of 100 and group them into a frequency chart. Change the class width or the distribution shape, and... Ages 16–17
Mathematics · Statistics Summary statistics of a data set – dragging data points A data sample is shown as a dot plot on a number line. Drag any point (or click 'Random') and watch the mean, median, quartiles Q₁, Q₂,... Ages 15–16
