The box plots below show attendance at a local movie theater and high school basketball games: two box plots shown. The top one is labeled Movies. Minimum at 60, Q1 at 65, median at 95, Q3 at 125, maximum at 150. The bottom box plot is labeled Basketball games. Minimum at 90, Q1 at 95, median at 125, Q3 at 145, maximum at 150. Which of the following best describes how to measure the spread of the data? The IQR is a better measure of spread for movies than it is for basketball games. The standard deviation is a better measure of spread for movies than it is for basketball games. T

    symmetric means the left half has the same shape as the right half examples:|dw:1434203598977:dw|

    for movies, the left side is very close to the box and the right side is far from the box that is not balanced

    so symmetric. I would use iqr for not symmetric and standard deviation for symmetric
