SOCR May 2008 Event - Use percentiles and measures of variability to analyze data
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.
