Answer :
Final answer:
The mean of the numbers 101, 102, 103, 103, 104, 203, 400 is calculated by adding all numbers and dividing by the total count, resulting in 159.42. The median is the middle number when the numbers are arranged in order, which in this case is 103.
Explanation:
In mathematics, the mean is calculated by adding all the numbers in a set and dividing by the count of numbers. For your set: 101, 102, 103 , 103 , 104, 203, 400, you get the mean by adding all the numbers (101 + 102 + 103 + 103 + 104 + 203 + 400 = 1116) and then dividing by 7 (the total count), which equals 159.42. This is the mean.
The median is the middle number in a data set when the numbers are arranged in order. If there is an odd number of observations, the median is the middle value. If there is an even number of observations, the median is the average of the two middle values. In this set, when arranged in order, the numbers are: 101, 102, 103, 103, 104, 203, 400. Since there are seven numbers (odd), the median is the fourth number, which is 103.
