How to find median - ISEE Middle Level Quantitative Reasoning

Each data set has five elements; the median is the element in the middle after the elements are arranged in ascending sequence, which both are. In each case, the median will be the third-highest element. Since in both data sets, this element is 100, the medians are equal.

The median of a data set with an even number of elements is the mean of the two elements in the middle when they are arranged in ascending order. The data set has six elements, so the median is the mean of the third-highest and third-lowest elements:

Arrange the scores from least to greatest.

There are an even number (eight) of scores, so the median is the arithmetic mean of the middle two scores, 72 and 73. This makes the median

To get the mean, add the numbers and divide by 8:

To get the median, find the mean of the fourth- and fifth-highest elements (the ones in the middle):

The difference is

It is impossible to tell which is greater.

For example, if all nine students weight 150 pounds, their median weight is 150, and their total weight is equal pounds.

If, however, their weights are

then the median of their weights - the middle value - is still 150 pounds, but the sum of their weights is

To find the median of a data set, you have to put the set in order from least to greatest . Then cross out one number from each side until you are left with the middle number, or the median. In this case, it's 10.

Arrange the scores from least to greatest.

There are an odd number (nine) of scores, so the median of the scores is the one that falls in the center - namely, 72.

To find the median of a data set, you have to put the set in order from least to greatest . Then cross out one number from each side until you are left with the middle number, or the median. In this case, it's 10.
