Front

What is the interquartile range (IQR)?

Back

The interquartile range (IQR) is a measure of statistical dispersion, representing the difference between the third quartile (Q3) and the first quartile (Q1) in a data set.

Front

How do you simplify the expression 2(4x - 7)?

Back

To simplify, distribute the 2: 2 * 4x - 2 * 7 = 8x - 14.

Front

What does it mean if a distribution is skewed right?

Back

In a right-skewed distribution, the tail on the right side is longer or fatter than the left side, indicating that the mean is greater than the median.

Front

How do you find the number of students greater than or equal to a certain height from a data set?

Back

Count the number of students whose height meets or exceeds the specified value.

Front

What is the difference between mean and median?

Back

The mean is the average of a data set, while the median is the middle value when the data is ordered.

Front

What is the solution set of the inequality -2x + 3 < 7?

Back

To solve, first subtract 3 from both sides: -2x < 4. Then divide by -2 (remember to flip the inequality): x > -2.

Front

What is a quartile in statistics?

Back

A quartile is a type of quantile that divides a ranked data set into four equal parts.

Front

How do you calculate the mean of a data set?

Back

Add all the values together and divide by the number of values.

Front

What is the purpose of simplifying algebraic expressions?

Back

Simplifying makes expressions easier to work with and understand, allowing for clearer problem-solving.

Front

What does it mean for a data set to be skewed?

Back

Skewness indicates the asymmetry of the distribution of values in a data set.
