What is a data set?

• A data set is a collection of related values or observations, often used for analysis.

• A data set is a random assortment of numbers without any specific meaning.

• A data set is a type of software used for data management.

• A data set is a graphical representation of data trends.

What is the purpose of a frequency table?

• To organize data for easier understanding and analysis of value distribution.

• To create visual representations of data only.

• To store data without any specific organization.

• To calculate the mean of a data set.

How do you measure length using a ruler?

• Align the object with the zero mark on the ruler and read the measurement at the other end of the object.

• Place the ruler on the object and measure from the middle to the end.

• Use the ruler to draw a line equal to the length of the object.

• Estimate the length by comparing it to the length of your hand.

What does it mean when a frequency table is incomplete?

• It shows all the data accurately.

• It does not show all the data or counts for certain ranges, making it difficult to understand the full data set.

• It includes extra data that is not relevant.

• It is perfectly organized and easy to read.

What is a frequency distribution?

• A method to calculate the mean of a data set.

• A frequency distribution shows how often each value occurs in a data set, often represented in a table or graph.

• A graphical representation of the relationship between two variables.

• A technique used to find the median of a data set.
