Answer:
mean = 6
median = 4.5
mode = 4
range = 13
Step-by-step explanation:
To find the mean, median, mode and range firstly place the numbers in ascending order.
2, 4, 7, 15, 7, 4, 5, 4
= 2, 4, 4, 4, 5, 7, 7, 15
Mean:
(Mean is the average of all the data in a set.)
[tex] \\ \tt2, 4, 4, 4, 5, 7, 7, 15[/tex]
[tex] \\ \tt = \frac{2 + 4 + 4 + 4 + 5 + 7 + 7 + 15}{8} [/tex]
[tex] \\ \tt = \frac{48}{8} [/tex]
[tex] \\ \bold{\tt = 6}[/tex]
Median:
(Median is the middle number of the set.)
2, 4, 4, 4, 5, 7, 7, 15
median
= 4+5/2
= 9/2
= 4.5
Mode:
(Mode is the number which appears multiple times.)
2, 4, 4, 4, 5, 7, 7, 15
mode = 4
Range:
(Range is the number which comes by subtracting the smallest number to the largest number.)
2, 4, 4, 4, 5, 7, 7, 15
Largest number = 15
Smallest number= 2
range
= 15-2
= 13
