Answer :
The right option is 26, which is median. The median (26) is the best measure of center for Kenny's case.
To determine the best measure of center, let's calculate the mean, median, and mode for the given data: 38, 30, 26, 25, 20, 24, 25, and 60.
Mean: (38 + 30 + 26 + 25 + 20 + 24 + 25 + 60) / 8 = 29.5
Median: Arranging the data in ascending order: 20, 24, 25, 25, 26, 30, 38, 60. The middle value is the median, which is 26.
Mode: The mode is the most frequent value, which is 25.
The median (26) is the best measure of center for Kenny's case. The mean is influenced by extreme values like the 60 minutes practice time, which can skew the result. The mode, in this case, doesn't provide a representative measure of the center since there are no repeated values other than 25. The median is not affected by extreme values and is a better representation of the typical practice time, making it the most suitable choice for Kenny to describe his time spent practicing the piano.
