What is a box and whisker plot?

Back

A box and whisker plot is a graphical representation of data that shows the distribution of a dataset based on a five-number summary: minimum, first quartile (Q1), median, third quartile (Q3), and maximum.

What does it mean to cross multiply in proportions?

Back

Cross multiplying is a method used to solve proportions. If you have a proportion a/b = c/d, you can cross multiply to get ad = bc.

Front

How can you organize data to solve a problem?

Back

You can organize data using a table, list, or by creating an equation to help visualize relationships and solve for unknowns.

Front

What is the purpose of using a probability tree?

Back

A probability tree is used to visualize all possible outcomes of a probability experiment, helping to calculate the probabilities of different events.

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 dataset?

Back

The median is the middle value of a dataset when it is ordered from least to greatest. If there is an even number of observations, the median is the average of the two middle numbers.

Front

What is a quartile in statistics?

Back

A quartile is a type of quantile that divides a dataset into four equal parts, with each part representing a fourth of the data.

Front

How do you find the range of a dataset?

Back

The range is found by subtracting the smallest value in the dataset from the largest value.

Front

What is the difference between independent and dependent events in probability?

Back

Independent events are those whose outcomes do not affect each other, while dependent events are those where the outcome of one event affects the outcome of another.

Front

What is an equation?

Back

An equation is a mathematical statement that asserts the equality of two expressions, typically containing variables and constants.
