May 22, 2024 · Using the formula for the median, when there is an even number of values, we need to take the mean value of the n/2 'th and (n+2)/2 'th values. So that's the 8th and 9th values, which are 71 and 74, respectively. Then we need to take the mean of these values: (71 + 74) / 2 = 145 / 2 = 72.5. So the median is 72.5.

Mean, median and mode are all measures of central tendency in statistics. In different ways they each tell us what value in a data set is typical or representative of the data set. The mean is the same as the average value of a data set and is found using a calculation. Add up all of the numbers and divide by the number of numbers in the data set. ...
Add up all data values to get the sumCount the number of values in your data setDivide the sum by the countThe median x~is the data value separating the upper half of a data set from the lower half. 1. Arrange data values from lowest to highest value 2. The median is the data value in the middle of the set 3. If there are 2 data values in the middle the median is the mean of those 2 values.
For the data set 1, 1, 2, 5, 6, 6, 9 the median is 5. For the data set 1, 1, 2, 6, 6, 9 the median is 4. Take the mean of 2 and 6 or, (2+6)/2 = 4.
Ordering a data set x1 ≤ x2 ≤ x3 ≤ ... ≤ xn from lowest to highest value, the median x~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 pwhere If n is even the median is the average of the values at positions p and p + 1where
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.
Potential Outliers are values that lie above the Upper Fence or below the Lower Fence of the sample set. Upper Fence = Q3 + 1.5 × Interquartile Range Lower Fence = Q1− 1.5 × Interquartile Range

In statistics, the mode is the value in a data set that has the highest number of recurrences. It is possible for a data set to be multimodal, meaning that it has more than one mode. For example: 2,10,21,23,23,38,38. Both 23 and 38 appear twice each, making them both a mode for the data set above. Similar to mean and median, the mode is used as ...
