How Do You Find The Mean, Median, Mode, And Range Of A Set Of Numbers?
If you are working with a set of numbers, you may need to find their mean, median, mode or range. Such problems tend to appear on the SAT, as well as other standardized tests. They also tend to show up in everyday math problems. Finding the mean, median, mode or range is relatively easy. You just have to remember which is which. Pick a set of numbers. Let’s use 89, 87, 57, 94 and 73. Find the mean of your group of numbers. To do this, simply find the average (the sum of the terms divided by the number of terms). So 89 + 87 + 57 + 94 + 73 = 400. And 400 ÷ 5 = 80. The mean is 80. Find the median of your set of numbers. Simply rearrange the numbers in numerical order and take the middle number. In numerical order, you have 57, 73, 87, 89 and 94. The median (or middle term) is 87. If a set has an even number of terms, find the median by taking the average (mean) of the two middle terms. Suppose it had been 57, 73, 87 and 89. You would find the median by taking the average of 73 and 87. 73
