Answer:
2.
Mode = 26.714285714286
Mean = 26
Median = 22
3.
Mode = 5.6153846153846
Mean = 5
Median = 3
4.
Mode = 53.75
Mean = 54
Median = 54
5.
Mode = 92.5
Mean = 92
Median = 88, 90, 91, 93, 95, 98

Explanation:
How to Find the Mean
1. Add up all data values to get the sum
2. Count the number of values in your data set
3. Divide the sum by the count
The mean is the same as the average value in a data set.
Mean Formula
The mean x̄ of a data set is the sum of all the data divided by the count n.
How to Find the Median
The median ˜ is the data value separating the upper half of a data set from the lower half.
Arrange data values from lowest to highest value
The median is the data value in the middle of the set
If there are 2 data values in the middle the median is the mean of those 2 values.
Median Formula
Ordering a data set x1 ≤ x2 ≤ x3 ≤ ... ≤ xn from lowest to highest value, the median ˜ is the data point separating the upper half of the data values from the lower half.
If the size of the data set n is odd the median is the value at position p where
If n is even the median is the average of the values at positions p and p + 1 where
How to Find the Mode
Mode is the value or values in the data set that occur most frequently.
For the data set 1, 1, 2, 5, 6, 6, 9 the mode is 1 and also 6.
