Additive, multiplicative and cat data

Front

What is the definition of additive data?

Back

Additive data refers to data that can be combined or summed up to provide a total. For example, if you have the number of apples and oranges, you can add them to find the total number of fruits.

Front

What is the definition of multiplicative data?

Back

Multiplicative data refers to data that involves multiplication to find a total or a product. For example, if you have 3 bags of apples with 4 apples in each bag, you multiply 3 by 4 to find the total number of apples.

Understanding percentages helps in comparing different quantities and understanding proportions, which is essential in data analysis.

Front

What is the difference between additive and multiplicative data?

Back

How do you interpret a bar graph?

Back

To interpret a bar graph, look at the height of each bar to understand the value it represents and compare the bars to see differences between categories.
