Variable- a number that can change. We use variables when collecting data.
Quantitative- a number value, a measurement
Qualitative- The categories used, a descriptive of the variable
- A pie chart is used when you have percentages
- A bar graph is used when comparing numerical values
- A dot plot is used to show a correlation between two variables
To make dot plots on excel, you follow the same instructions (making pie and bar graphs) in the video above, but you pick the graph that represents a dot plot.
*As said above, dot plots can be used to show correlation between data. When used in excel, it shows clear correlations, and can help the viewer to better understand the connection between your data recieved.
