Displaying Statistics through Box Plots & Dot Plots.
Use the data below to construct a Dot Plot and Box Plot. “Mrs. A records the heights of some of her students in inches and records the values below.” 72 56 62 62 70 60 65 66 66 71 61 68 62 62
Determine the mean, median, mode and range for the set of data above.
Dot Plot: Measures frequency. Create a number line that includes the least and greatest values of your data. Then place a dot on the number line each time the measurement occurs.
Box Plot: Create a number line that includes the least and greatest values of your data. Place a dot on the maximum and minimum value, as well as on the 1st, 2nd and 3rd quartile. The 2nd quartile is the median!
