SOCR CensusAtSchool International Workshop - Percentiles and measures of data variability
Compute different measures of spread, including the range, standard deviation, and interquartile range
Compare the effectiveness of different measures of spread, including the range, standard deviation, and interquartile range in specific situations
Use percentiles to summarize the distribution of a numerical variable
Copy the first 200 measurements of the Human Height and Weight Dataset into the SOCR Histogram Chart, map the Heights column and choose the bin-size to be 0.1 - this corresponds roughly to plotting the percentiles for this data.
Use histograms to obtain percentiles
