DSR.10.1,2Compare & Contrast Data Distributions

Front

What is the range of a data set?

Back

The range is the difference between the highest and lowest values in a data set.

Front

What is the interquartile range (IQR)?

Back

The interquartile range (IQR) is the difference between the first quartile (Q1) and the third quartile (Q3) in a data set, representing the middle 50% of the data.

Front

How do you determine the median of a data set?

Back

To find the median, arrange the data in numerical order and identify the middle value. If there is an even number of values, the median is the average of the two middle values.

Front

What does it mean if a data set is symmetric?

Back

A symmetric data set has a balanced distribution where the left and right sides of the data are mirror images of each other.

Front

What is a box plot?

Back

A box plot is a graphical representation of a data set that shows the median, quartiles, and potential outliers.

Front

What is the difference between mean and median?

Back

The mean is the average of all values in a data set, while the median is the middle value when the data is ordered.

Front

What does a greater range indicate about a data set?

Back

A greater range indicates a wider spread of values in the data set, meaning there is more variability.

Front

How can you compare the centers of two data sets?

Back

You can compare the centers of two data sets by looking at their means or medians.

Front

What is a dot plot?

Back

A dot plot is a simple graphical display that uses dots to represent the frequency of values in a data set.

Front

What does it mean if one data set has a higher median than another?

Back

If one data set has a higher median, it indicates that the center value of that data set is greater than that of the other data set.
