Find the median and mean of the data set below:
27
,
36
,
44
,
7
,
17
27,36,44,7,17
To find the median, we first need to put the numbers in order from least to greatest:
7, 17, 27, 36, 44
The median is the middle number, which in this case is 27. Therefore, the median of the data set is 27.
To find the mean, we add up all the numbers and divide by the total number of numbers:
(27 + 36 + 44 + 7 + 17) ÷ 5 = 26.2
Therefore, the mean of the data set is 26.2.
To find the median and mean of the given data set, follow these steps:
Step 1: Arrange the data in ascending order:
7, 17, 27, 36, 44
Step 2: Find the median:
Since we have an odd number of data points (5 in this case), the median is the middle value.
The middle value is 27, so the median is 27.
Step 3: Find the mean:
To find the mean, sum up all the values and divide it by the total number of values.
Mean = (7 + 17 + 27 + 36 + 44) / 5
Mean = 131 / 5
Mean = 26.2
Therefore, the median is 27 and the mean is 26.2.
