Answer:
19 is the range.
17.4 is the mean.
20.5 is the median.
24 is the mode.
Step-by-step explanation:
- Range - The difference of the largest number and the smallest number
- Mean - To calculate the mean, add up all the numbers, then, divide the sum by the count.
- Median - The "middle" number after putting the numbers in numerical order
- Mode - The most frequently appearing numbers
-------------------------------------------------------------------------------------------------------------
22, 5, 22, 13, 12, 24, 24, 9, 24, 19.
Now that we know what these words mean, we can solve this.
Range: 24 - 5 = 19
19 is the range.
-------------------------------------------------------------------------------------------------------------
Now, let's calculate the mean.
Mean: 22 + 5 + 22 + 13 + 12 + 24 + 24 + 9 + 24 + 19 = 174
There are 10 numbers in total.
174 ÷ 10 = 17.4
17.4 is the mean.
-------------------------------------------------------------------------------------------------------------
5, 9, 12, 13, 19, 22, 22, 24, 24, 24
In this case, there are two medians.
So to find the median, we have to add both the medians of this data set, then, divide the sum by 2.
19 + 22 = 41
41 ÷ 2 = 20.5
20.5 is the median.
-------------------------------------------------------------------------------------------------------------
5, 9, 12, 13, 19, 22, 22, 24, 24, 24
24 appears the most; 24 is the mode.
