It is 85, the middle value, between 80 and 90.
Median of the set = arithmetic mean of 75 and 85 = 80
The mean is 85.5 The median is 88.5 The mode is 90
The median of those numbers is 90.
Write the data in an increasing order:40 60 79 80 90 90 98 99Since the number of data is even, the median will be the average of the two data that are in the middle (80 and 90).So the median of the data is 85, (80 + 90)/2.
the median is 86. What you do is put the numbers in order from least to greatest and cross one off from each side till you get to the middle number. 80 85 86 90 94
100,90,85, 90,80,75,80.90. Rearrange the terms in rank order. 75,80,80,85,90,90,90,100. MEAN : Add all the terms together and divide by the number of terms. Hence:- (75+80+80+85+90+90+90,+100)/8 => 690/8 = 86.25 MEDIAN : Is the Absolute middle term. Since there are an even number of terms, we take the two middle terms, which are 85 & 90. (NB This leaves three terms to the left of '85' and three terms to the right of '90'. ). Add these two terms and divide by '2'. Hence (85+90) / 2 = 87.5 MODE : Is the most frequent term. The one term that appears most often. In this case it is '90', as there are three lots of '90', but only two lots of 80, and only one each of the remaining terms. = 90. .
The MEDIAN is the number in the middle. In order to find the median, you have to put the values in order from lowest to highest, then find the number that is exactly in the middle. For example : 80 85 90 90 90 100 ^ since there is an even number of values, the MEDIAN is between these two, or it is 90. Notice that there is exactly the same number of values above the median as below it! Its that simple.
