Mean, Median, Mode Flashcard

Front

What is the definition of Mean?

Back

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

Front

What is the definition of Median?

Back

The median is the middle value in a data set when the numbers are arranged in ascending order. If there is an even number of observations, the median is the average of the two middle numbers.

Front

What is the definition of Mode?

Back

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

Front

How do you calculate the Range of a data set?

Back

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

Front

What is the Interquartile Range (IQR)?

Back

The interquartile range 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 find the Mode in a data set?

Back

To find the mode, identify the number that appears most frequently. If no number repeats, the data set has no mode.

Front

What is a frequency distribution?

Back

A frequency distribution is a summary of how often each value occurs in a data set, often represented in a table or graph.

Front

What is a histogram?

Back

A histogram is a graphical representation of the frequency distribution of numerical data, using bars to show the frequency of data within certain intervals.

Front

What does it mean if a data set is bimodal?

Back

A bimodal data set has two modes, meaning there are two values that appear with the highest frequency.

Front

How do you determine the greatest number of employees in a frequency distribution?

Back

To determine the greatest number of employees, compare the frequencies of each interval and identify the one with the highest count.
