Find the mean and the median.–2, 7/4−, 3/4, 4,?
Answer:
The mean is the arithmetic average
(-2 + -7/4 + 3/4 + 4)/4 = .25
The median is the middle number. When there are an even number of terms then it is the mean of the two middle numbers.
(-7/4 + 3/4)/2 = -.5
-2, -7/4, 3/4, 4?
mean (3/4+ 4-2 -7/4 )/4
median (3/4-7/4 )/4
Barkley is right. When you have odd number of numbers pick the middle. So line up or sort your numbers and pick either the middle the average of the two middle ones.
