# Calculate mean, median, mode and range for sets of data. Interpret these statistics in the context of data(ACMSP171)

LO: To calculate the mean, median, mode and range for a set of data.
Know:

• How to add and divide numbers
• How to order numbers from ascending/descending order
• How to do a tally table

Understand:

• That statistics can be used to help organise data

Do:

• I can calculate the mean for a set of data.
• I can calculate the median for a set of data.

# Visual Representations # Mean

### 1) add all of the numbers 2) divide by the number of items in the data set. # Median

### 1) arrange the numbers in order (ascending/descending doesn’t really matter) 2) find the middle number 3) if there are 2 middle numbers, you will have to find the average between the two numbers. ### 1 middle number # Mode

### Mode is also known as the “most popular/common” number/item. # Range

### Range is the difference between the lowest (minimum) and highest (maximum) values or the spread of values of your data. # ACARA Work Samples # Student Generated Videos
