The median is 84.
Median: 80 Mode: 72, 80, 120, 98, 78, 84, 77
It is 87, the number halfway between the two middle numbers.
The median is the average of 85 and 87, that is 86.The median is the average of 85 and 87, that is 86.The median is the average of 85 and 87, that is 86.The median is the average of 85 and 87, that is 86.
[80/100]*84 =67.2
The median is 84.

[80/100]*84 =67.2
It is: 84/74 times 100 = 113.5% rounded to one decimal place
When the data is arranged in ascending order, the middle numbers are 88 and 90. Take the mean of these, which is 89, as the median.
80, 84, 88, 92, 96, 100
The median is 94.
The mean is now: (74+76+77+78+79+80+80+82+84)/9 = 78.889. Since 50 is an outlier, the overall representation of the test score becomes more accurate since the majority of values lie between 74 and 84.
74=((78*4)+(84*4)+(74*2)+(80*3))/(4+5+2+3)3.5=(4+5+2+3)/4
8 numbers, so the median is the mean average of the 4th and 5th numbers. 4th number is 86 5th number is 86 median = (86 + 86) ÷ 2 = 86.
