What is a box plot?

Back

A box plot is a graphical representation of a dataset that shows the minimum, first quartile (Q1), median, third quartile (Q3), and maximum values.

What does the mean represent in a dataset?

Back

The mean is the average of a set of numbers, calculated by adding all the values together and dividing by the number of values.

Front

How do you find the median of a dataset?

Back

To find the median, arrange the numbers in 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 is mode in statistics?

Back

The mode is the value that appears most frequently in a dataset.

Front

What is a histogram?

Back

A histogram is a type of bar graph that represents the frequency distribution of numerical data, showing 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 uses dots to represent the frequency of data points in a dataset.

Front

How do you calculate the range of a dataset?

Back

The range is calculated by subtracting the smallest value from the largest value in the dataset.

Front

What is the upper quartile (Q3)?

Back

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

Front

What does it mean if a club has a smaller spread?

Back

A smaller spread indicates that the data points (e.g., scores, measurements) are closer together, showing less variability.

Front

How do you interpret the intervals in a histogram?

Back

Intervals in a histogram represent ranges of data values, and the height of each bar shows the number of data points that fall within each interval.
