Find the median and mean of the data set below:
18, 21, 23, 34, 37, 48, 50
To find the median, we need to find the middle number in the set. To do this, we can list the numbers in order from smallest to largest:
18, 21, 23, 34, 37, 48, 50
The middle number is 34, so the median is 34.
To find the mean, we can add up all the numbers and divide by the total number of values:
(18 + 21 + 23 + 34 + 37 + 48 + 50) / 7 = 31.86
So the mean is 31.86.
To find the median of a data set, you need to arrange the numbers in ascending order and then find the middle number.
Arranging the data set in ascending order gives us: 18, 21, 23, 34, 37, 48, 50
Since there are 7 numbers in the data set, the middle number is the 4th number.
Therefore, the median of the data set is 34.
To find the mean of a data set, you need to add up all the numbers in the set and then divide by the total number of values.
Adding up the numbers in the data set gives us: 18 + 21 + 23 + 34 + 37 + 48 + 50 = 231.
Since there are 7 numbers in the data set, we divide the sum (231) by 7.
Therefore, the mean of the data set is 33.
