Objective: Students will be able to 1) Create a box-and-whisker plot, 2) Interpret a box-and-whisker plot, and Identify cumulative frequency. How do I interpret a box-and-whisker plot? I 1. What does the x-axis show? Boys 2. What does the y-axis represent? 3. What does the length of Girls each of the lines (red and green) mean? 4. Does the size of the box 2. 8 10 12 14 16 18 20 22 24 Time (s) matter? How to create a box-and-whisker plot: To draw a box-and-whisker plot you need five pieces of information, called the five-number summary: the smallest value, the lower quartile (LQ), the median, the upper quartile (U0) and the largest value. An outlier is a value that is much smaller or much larger than the other values. An outlier is a point less than the LQ-1.5x 1QR or greater than the UQ+1.5xIQR.
b. Calculate the range. Range= c. Calculate the interquartile range, IQR. IQR= d. State whether the distribution is symmetric, skewed left, or skewed right. Symmetric Skewed left Skewed right e. Would you expect the mean to be greater than, equal, or less than the median? Equal Greater than Less than
