Alg 1: Keystone Algebra Review #3

Front

What does it mean to multiply probabilities in an 'and' problem?

Back

In probability, when you have an 'and' problem, you multiply the probabilities of the individual events occurring together.

Front

What is the median in a set of numbers?

Back

The median is the middle number in a sorted list of numbers. If there is an even number of values, the median is the average of the two middle numbers.

Front

What is the range in a set of data?

Back

The range is the difference between the highest and lowest values in a data set.

Front

What is the vertical line test?

Back

The vertical line test is a method to determine if a curve is a function. If a vertical line intersects the curve at more than one point, it is not a function.

Front

What is a box and whisker plot?

Back

A box and whisker plot is a graphical representation of data that shows the distribution through their quartiles, highlighting the median, lower quartile, upper quartile, and any outliers.

Front

How do you find the probability of independent events?

Back

To find the probability of independent events occurring together, multiply their individual probabilities.

Front

What is the difference between mean and median?

Back

The mean is the average of a set of numbers, while the median is the middle value when the numbers are arranged in order.

Front

What does it mean for a function to be linear?

Back

A function is linear if it can be graphically represented as a straight line, which means it has a constant rate of change.

Front

What are outliers in a data set?

Back

Outliers are values that are significantly higher or lower than the other values in a data set, which can skew the results.

Front

What is the purpose of a scatter plot?

Back

A scatter plot is used to determine the relationship between two variables by displaying data points on a Cartesian plane.
