Unit 2 Final Exam Math Review

Front

How do you calculate the mean of a set of values?

Back

The mean is calculated by adding all the values together and dividing by the number of values. For example, for values C24 and C35, use =average(C24,C35).

Front

What type of function is represented by a U-shaped graph?

Back

A quadratic function is represented by a U-shaped graph.

Front

What is interpolation in the context of data analysis?

Back

Interpolation is the process of estimating unknown values that fall within the range of known data points.

Front

How do you calculate the maximum value in a range of cells?

Back

The maximum value is calculated using the formula =maximum(C24:C35).

Front

What does a box plot represent in statistics?

Back

A box plot visually represents the distribution of a dataset, showing the median, quartiles, and potential outliers.

Front

What is the first quartile in a dataset?

Back

The first quartile (Q1) is the median of the lower half of the dataset, representing the 25th percentile.

Front

What is the difference between interpolation and extrapolation?

Back

Interpolation estimates values within the range of known data, while extrapolation estimates values outside that range.

Front

How do you identify a radical function?

Back

A radical function includes a variable under a root, such as f(x) = √x.

Front

What is the formula for calculating the median of a dataset?

Back

To find the median, arrange the data in order and select the middle value. If there are two middle values, average them.

Front

What is a linear function?

Back

A linear function is a function that graphs to a straight line, represented by the equation y = mx + b.
