• can be measured

  

Qualitative Data

• categorical and descriptive

• can't be measured

  

Quantitative data is usually preferred for data analytics in Excel. You can gather quantitative data through polls, surveys, observations, experiments, and interviews.

Use formulas to find the sum, average, minimum, and maximum of the collected data.

  2. Enter a SUM function by typing =SUM(B2:B5)

  3. Press Enter to get the total sales

  1. Select the empty cell B7 (where the average amount will appear)

  2. Enter an AVERAGE function by typing =AVERAGE(B2:B5)

  3. Press Enter to get the average sales

• She uses the MIN formula to find the minimum sales as follows:

  1. Select the empty cell B7 (where the minimum amount will appear)

  2. Enter a MIN function by typing =MIN(B2:B5)

  3. Press Enter to get the Min sales

• She uses the MAX formula to find the maximum sales as follows:

1. Select the empty cell B7 (where the maximum amount will appear)

2. Enter a MAX function by typing =MAX(B2:B5)

What is a cell reference?

A cell reference is a combination of a column letter and a row number that identifies a cell on a spreadsheet.

There are two types of cell references:

• Relative references

• Absolute references

What's the difference?

• Relative references change when a formula is copied to another cell.

• Absolute references remain unchanged wherever they're copied.

Watch this video to learn how to use these two types of references.

Amelia, the clothing store owner, uses cell references in Excel when calculating item costs after tax.

Create charts to visualize your data for reports or presentations.

Take a closer look at the most common chart types:

A pie chart shows the proportion of items to the total.

A line chart shows continuous data over time.

A bar chart typically displays values along the horizontal axis and categories along the vertical axis.

A column chart typically displays values along the vertical axis and categories along the horizontal axis.

Creating charts in Excel is so easy!

1. Select all the rows and columns you want to tabulate in your charts (A1:B7 for the chart below)

2. Select Insert > Recommended Charts

3. Select a chart from the drop-down menu
