Unit 6 Statistics Test Review

Front

What is a box-and-whisker plot?

Back

A box-and-whisker plot is a graphical representation of a dataset that displays the minimum, first quartile, median, third quartile, and maximum values.

Front

How do you find the median of a dataset?

Back

To find the median, arrange the data values in ascending 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 does it mean if a distribution is skewed right?

Back

A right-skewed distribution has a longer tail on the right side, indicating that there are a few higher values that pull the mean to the right of the median.

Front

What is the mode of a dataset?

Back

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

Front

How do you create a dot plot?

Back

A dot plot is created by placing a dot above a number line for each value in the dataset, allowing for a visual representation of the frequency of each value.

Front

What are quartiles in statistics?

Back

Quartiles are values that divide a dataset into four equal parts, with the first quartile (Q1) being the median of the lower half, the second quartile (Q2) being the median, and the third quartile (Q3) being the median of the upper half.

Front

What is the range of a dataset?

Back

The range is the difference between the maximum and minimum values in a dataset.

Front

How do you interpret a skewed distribution?

Back

In a skewed distribution, the mean is affected by extreme values, which can provide insights into the data's behavior and trends.

Front

What is the difference between mean and median?

Back

The mean is the average of all data values, while the median is the middle value when the data is ordered.

Front

What is a frequency distribution?

Back

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