What is the Lower Quartile (Q1)?

Back

The Lower Quartile (Q1) is the median of the lower half of a data set, which separates the lowest 25% of the data from the rest.

Front

How do you find the Upper Quartile (Q3)?

Back

The Upper Quartile (Q3) is the median of the upper half of a data set, which separates the highest 25% of the data from the rest.

Front

What is the Mean of a data set?

Back

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

Front

What is the Mode of a data set?

Back

The Mode is the number that appears most frequently in a data set.

Front

What is Causation in statistics?

Back

Causation indicates that one event is the result of the occurrence of another event, meaning there is a direct cause-and-effect relationship.

How do you calculate the Lower Quartile for the data set: 84, 88, 72, 74, 98, 16, 94?

Back

First, arrange the data in ascending order: 16, 72, 74, 84, 88, 94, 98. The Lower Quartile (Q1) is 72.

Front

How do you calculate the Upper Quartile for the data set: 84, 88, 72, 74, 98, 16, 94?

Back

First, arrange the data in ascending order: 16, 72, 74, 84, 88, 94, 98. The Upper Quartile (Q3) is 94.

Front

How do you find the Mean of the data set: 84, 88, 72, 74, 98, 16, 94?

Back

Add all the numbers: 84 + 88 + 72 + 74 + 98 + 16 + 94 = 526. Divide by the count of numbers (7): 526 / 7 = 75.1.

Front

What is the first step to find the Mode of the data set: 12, 10, 10, 10, 13, 12, 11, 13, 10, 12, 13?

Back

Count the frequency of each number. The number that appears most frequently is the Mode.

Front

What is the difference between correlation and causation?

Back

Correlation indicates a relationship between two variables, while causation indicates that one variable directly affects the other.
