Find the mean, median, and modes of the data set: 91, 93, 89, 97, 89, 98, 94, 93.(2 points)
The mean is
.
The median is
.
The first mode in the data set is
.
The second mode in the data set is
Mean: (91+93+89+97+89+98+94+93)/8 = 92.25
To find the median, we first need to arrange the data in order: 89, 89, 91, 93, 93, 94, 97, 98.
Since there are 8 numbers, the median will be the average of the 4th and 5th numbers: (93+94)/2 = 93.5
Mode: The mode is the number that appears most frequently in the data set. In this case, both 89 and 93 appear twice, so they are both modes.
