To find the median, order the numbers in the data set from least to greatest (or greatest to least, either one works) and then find the number in the middle. If there are 2 numbers in the middle, find their mean.
Step 2: Find the median (middle number). The median is the number in the center. Count in from each side equally to find the middle number. 76, 78, 82, 84, 88, 90, 92, 94, 98, <span>100 </span>78, 82, 84, 88, 90, 92, 94, 98 82, 84, 88, 90, 92, 94 84, 88, 90, 92 88, 90 88 and 90 are the middle numbers. Since there are 2 numbers in the middle, we must find their mean.
Step 3: Find the mean of the 2 middle numbers. Mean is also known as average. To find this, add up the numbers and then divide by the amount of numbers there are. In this case, that means adding 88 and 90 then dividing their sum by 2. This can be represented by the equation (88 + 90) ÷ 2. 88 + 90 = 178 178 ÷ 2 = 89 89 is the final answer, it is the median.
The < and > signs mean lesser and greater than. = means equal(s). The signs will always look like they are eating the bigger value. For example: 12<29 Twelve is lesser than twenty-nine, or 29>12 Twenty-nine is greater than twelve. An equation uses an equal sign 12+8=20 When you're using all of them, it can look like this: 1<n<29 This is read as "one is lesser than n which is lesser than 29". These can be used to determine the lengths of the sides of a triangle. In this case, n must be between 1 and 29 for it to be the side of a triangle.
