A cumulative chart helps us understand how a quantity increases or decreases over a specific period. It's like a record of all the changes, showing us how the total amount changes with each unit or event.
Imagine a chart with the following information:
Unit 1: 10 units
Unit 2: 15 units
Unit 3: 20 units
Unit 4: 25 units
The chart tells us that the quantity increases by 5 units from one unit to the next. This means the total amount increases by 5 units from 10 to 15, 15 to 20, 20 to 25.
Cumulative charts can be used to answer questions like:
What was the total amount at the beginning of the period?
What was the average increase or decrease per unit?
How did the total amount change over time?
Cumulative charts are a powerful tool for interpreting growth and change in a dataset. They allow us to easily identify trends and patterns in the data, making it easier to draw conclusions about the underlying factors
