What is a box plot?

Back

A box plot is a graphical representation of data that shows the distribution through five summary statistics: minimum, first quartile (Q1), median (Q2), third quartile (Q3), and maximum.

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

How do you find the mode of a data set?

Back

The mode is the value that appears most frequently in a data set. A data set may have one mode, more than one mode, or no mode at all.

Front

What is a histogram?

Back

A histogram is a type of bar graph that represents the frequency distribution of numerical data. It shows how many data points fall within specified ranges (bins).

Front

What is a dot plot?

Back

A dot plot is a simple statistical chart that consists of dots representing the frequency of data points. Each dot represents one observation.

Front

What is the lower quartile (Q1)?

Back

The lower quartile (Q1) is the median of the lower half of a data set. It represents the 25th percentile.

Front

What is the upper quartile (Q3)?

Back

The upper quartile (Q3) is the median of the upper half of a data set. It represents the 75th percentile.

Front

What does it mean if data is skewed left?

Back

If data is skewed left, it means that the left tail of the distribution is longer or fatter than the right tail, indicating that there are a few lower values pulling the mean down.

Front

What is the range of a data set?

Back

The range is the difference between the maximum and minimum values in a data set. It shows the spread of the data.

Front

How do you calculate the mean of a data set?

Back

To calculate the mean, add all the values in the data set together and then divide by the number of values.
