Find the mean, median, mode, and range of this data: 49, 49, 54, 55, 52, 49, 55. if necessary, round to the nearest tenth.

Mean=51.86

Mode=49

Median=52

Range=6

Step-by-step explanation:

We are given a data set:

49, 49, 54, 55, 52, 49, 55

We arrange this in ascending order:

49,49,49,52,54,55,55

Mean=sum of all the elements/number of elements

         =49+49+49+52+54+55+55/7

Mean  =51.86

Mode is that element of the data set which has highest frequency i.e. the element which comes most.

Hence, Mode=49

Median is the middle element of the data set arranged in ascending order.

Hence, Median=52

Range=highest element-lowest element

Hence, Range=55-49

            Range=6

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
