The table shows the battery lives, in hours, of ten Brand A batteries and ten Brand B batteries. Which would be the best measure of variability to use to compare the data? Only Brand A data is symmetric, so standard deviation is the best measure to compare variability. Only Brand B data is symmetric, so the median is the best measure to compare variability. Both distributions are symmetric, so the mean is the best measure to compare variability. Both distributions are skewed left, so the interquartile range is the best measure to compare variability.
