Question

19, 19, 27, 93, 121, 203, 291, 372, 389, 405, 453, 493, 549, 565, 775

Find the (median, mode, range, and mean) of the data set, and pls show how to find each of them.

Answer 1

Mean: 298.87
Mode: 19
Median: 372
Range: 756

Explanation:

Mean is the sum of terms over the total number of terms.
(19+19+27+93+121+203+372+389+405+453+493+549+565+775)/15 = 298.87
Mode is the most repeated term or value in the set.
(19,19,27,93,121,203,372,389,405,453,493,549,565,775) the only value repeated is 19
Median is the middle of the data set.
With 15 values the middle is 372
Range is the extent of all values between smallest and largest values
Largest values is 775, and the smallest is 19. 775-19 = 756

Answer 2

mean: 318.266

median: 372

mode: 19

range: 756

Explanation:

to find the mean or the average, add all the numbers up and divide them by how many there are. example: 5 + 5 + 5 = 15 ÷ 3 = 4

to find the mode, all you have to do is find the number that is most common, there can be multiple modes

for the range, you subtract the smallest number from the largest

finally, to get the median, you put all the numbers in order from smallest to biggest and make your way to the number in the middle, if there are two numbers in the middle, add them up and divide them by two
