When should relative frequencies be used when comparing two data sets?
When comparing large data sets.
How is a bar graph used to display data?
It shows the amount of the surveyed matter or other sets of data. They are good comparing sets of the data that just have an amount.
When is a bar graph useful?
when a sets of data can be separated by 2 orders of variables, which are the independent & dependent variables.
What does a double bar graph compare in two sets of data?

What is the significance of data models?
The model's main function is to help us understand the complexities of the real-world environment. Within the database environment, a data model represents data structures and their characteristics, relations, constraints, and transformations. Good database design uses an appropriate data model as its foundation. Plus, a data model provides a blueprint of the data that is required for a functional system.
What is a grouped frequency distribution used for?

What is data sets?
They are groups of data.
Why f represents the graph of a function?
Because f represents a function.
When is a key necessary on a graph?
A key can make it easier to interpret the data sets that each part of the graph represents, especially if there is no room in the graph area for labels.
Will a set of data always have a mode?
No, because sometimes sets of data can have different numbers and other sets of data can have modes in them.
Does all data have a mean median or mode?

The description of the relationship between two data sets?
Comparing the relationship of two data sets is needed to see which of the two sets have more life distribution. Two data sets involve the use of simple plotting and contour plots.
