Median: 80 Mode: 72, 80, 120, 98, 78, 84, 77
To start with we need to find what the current range median mode and mean is for the first 4 results: 80, 88, 94, 98 Current range = 98-80 =18 current median = (88+94)/2 =91 Current mode= there is not one most frequent score so they're all the mode Current mean=(80+88+94+98)/4 =90 When we add the additional score of 85 We have 80,85,88,94,98 Range doesn't change (highest score and lowest score is still the same) Median (middle score) is now 88. This has decreased from before Mode: There is still no one most frequent score as no exam mark occurs twice Mean = (80+85+88+94+98)/5 = 89 This has also decreased. Hope this helps
The median is 84.
It is 80, the middle number when they are arranged in order.
The median of those numbers is 90.
The mean is 85.5 The median is 88.5 The mode is 90
Median: 80 Mode: 72, 80, 120, 98, 78, 84, 77
The range is 114, which is the difference between the highest and lowest numbers which are 120 and 6. The median is 15, which is the middle value when they are listed in order. The mode is 10, which is the most frequently occurring number. It occurs 3 times.Range = 114Median = 15Mode = 10.
The mean is: 81.6 The median is: 81 Its mode is: 81 and 83 because its bi-modal

80
The median of those numbers is 90.
10, 11, 15, 19, 19, 19, 25, 27, 80 Median: 19 Mean: 25 Mode: 19
Not by itself. In the sequence 80, 82, 95, 100, 106... 95 is the median.
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. .
