given the following hourly wages 3, 2, 10, calculate the following:

arithmetic mean

median

mode

range

standard deviation

meaning of the answer (standard deviation)

Step 1

Given data

3, 2, 10

**Arithmetic mean **

The arithmetic mean (also called the mean*) *is the most commonly used measure of central tendency. It is calculated by summing up the observed numerical values of a variable in a set of data and then by dividing the total by the number of observations involved.

*x̅* = (Σ*x _{i}*)/

**Median **

The median is the middle-most observation in an ordered (in an ascending or descending order) data set. For an odd number of observations, *n* in the data set, the median is the observation in the (*n* + 1)/2^{th} position. For an even number of observations, *n* in the data set, the median is the observation in the average of the observations in the (*n*/2)^{th} position and the (*n*/2 + 1)^{th} position

2,3,10

Median = 3

Step 2

**Mode**

Mode is the most frequently occurring value in the data set. Here we do not have a mode because each value occurs once.

**Range **

It is difference between the highest and lowest valu...
