Question

What's the mean, median, and mode of 3, 5, 1, 5, 1, 1, 2, 3, 15.

Answer 1

Answer:

mean = 4

Median = 3

Mode = 1

Step-by-step explanation:

first let’s arrange the numbers in ascending order:

1 , 1 , 1 , 2 , 3 , 3 , 5 , 5 , 15

The median is the number that’s comes in the middle of the data set: median = 3 ( the fifth number in the data set)

1 , 1 , 1 , 2 , 3, 3 , 5 , 5 , 15

The mode is the number that repeats the most ⇒ mode = 1 (repeated 3 times)

the mean= sum of total number/total number of occurence

mean = 1+1+1+2+3+3+5+5+15/9

mean= 36/9= 4

Answer 2

Answer:

mean = 4

Median = 3

Mode = 1

Step-by-step explanation:

first let’s arrange the numbers from least to highest:

1 , 1 , 1 , 2 , 3 , 3 , 5 , 5 , 15

=====================

The median is the number that’s comes in the middle of the data set ⇒ median = 3  ( the fifth number in the data set)

1 , 1 , 1 , 2 , 3, 3 , 5 , 5 , 15

The mode is the number that repeats the most ⇒ mode = 1  (repeated 3 times)

$\text{the mean} =\frac{1+1+1+2+3+3+5+5+15}{9} = \frac{36}{9}=4$
