20. Find the mean, median, and mode for the following
data set:
83 98 22 89 99 98

a. Mean = 81.5

b. Median = 93.5

c. Mode = 98

Step-by-step explanation:

Given the following data;

x = 83, 98, 22, 89, 99, 98

F(x) = 83 + 98 + 22 + 89 + 99 + 98

F(x) = 489

Number of items, n = 6

a. To find the mean;

Mean = F(x)/n

Mean = 489/6

Mean = 81.5

b. To find the median;

Median refers to the middle number of a sorted data. Thus, we would arrange the number in an ascending order and choose the middle number.

x = 22, 83, 89, 98, 98, 99

Middle numbers = 89 and 98

Median = (89 + 98)/2

Median = 187/2

Median = 93.5

c. To find the mode;

Mode is the number which appeared the most in the series.

Mode = 98

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
