What is a box-and-whisker plot?

Back

A box-and-whisker plot is a graphical representation of data that shows the distribution through five summary statistics: minimum, first quartile (Q1), median, third quartile (Q3), and maximum.

Front

What does the median represent in a data set?

Back

The median is the middle value of a data set when it is ordered from least to greatest. It divides the data into two equal halves.

Front

What is the upper quartile in a data set?

Back

The upper quartile (Q3) is the median of the upper half of a data set, representing the value below which 75% of the data falls.

Front

How do you find the median of a data set with an even number of values?

Back

To find the median of a data set with an even number of values, average the two middle numbers after sorting the data.

Front

What is a dot plot?

Back

A dot plot is a simple statistical chart that consists of dots plotted above a number line, representing the frequency of data points.

Front

What is the sample size in a survey?

Back

The sample size is the number of individuals or observations included in a survey or study.

Front

What does it mean if 50% of people paid less than a certain amount?

Back

It means that the median value of the data set is that certain amount, indicating that half of the data points are below it.

Front

How do you interpret the upper quartile in a box-and-whisker plot?

Back

The upper quartile indicates that 75% of the data points are below this value, showing the higher end of the data distribution.

Front

What is the significance of the median in data analysis?

Back

The median is significant because it provides a measure of central tendency that is not affected by extreme values (outliers).

Front

How can you determine the range of a data set?

Back

The range is determined by subtracting the minimum value from the maximum value in the data set.
