Detailed Data Analysis

Question 1

Data Analysis - Measures of Central Tendency - Mean

Answer 1

Arithmetic average - add up all values of the variables and divide by the total number of values

Question 2

Data Analysis - Measures of Central Tendency - Mode

Answer 2

The most frequently-occurring value of a variable, simply which value comes up most

Question 3

Data Analysis - Measures of Central Tendency - Median

Answer 3

The mid-point - order all the values of a variable from smallest to largest, then take middle value, as 50% equal to the median or smaller and 50% equal or larger

Question 4

Data Analysis - Measures of Central Tendency - What works best

Answer 4

Mean and Median work best with Continuous variables, things measured on a precise scale such as percentages or age, where for Categorical variables, like gender or political party preference, Mode works best and is only tool for these variables
