5 Number Summary and Probability

Front

What is the 5 Number Summary?

Back

The 5 Number Summary consists of the minimum, first quartile (Q1), median, third quartile (Q3), and maximum of a data set.

How do you calculate the median of a data set?

Back

To find the median, arrange the data in ascending order and locate the middle value. If there is an even number of values, average the two middle values.

Front

What is a quartile?

Back

A quartile is a type of quantile that divides a data set into four equal parts, with Q1 being the first quartile, Q2 the median, and Q3 the third quartile.

Front

What is the third quartile (Q3)?

Back

The third quartile (Q3) is the value that separates the highest 25% of the data from the rest.

Front

What does it mean for two events to be mutually exclusive?

Back

Two events are mutually exclusive if they cannot occur at the same time.

Front

What is the probability of an event?

Back

The probability of an event is a measure of the likelihood that the event will occur, expressed as a number between 0 and 1.

Front

How do you calculate the probability of selecting a specific outcome from a set?

Back

The probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

Front

What is the formula for calculating the probability of two mutually exclusive events?

Back

For mutually exclusive events A and B, P(A or B) = P(A) + P(B).

Front

What is the first quartile (Q1)?

Back

The first quartile (Q1) is the value that separates the lowest 25% of the data from the rest.

Front

What does it mean for two events to be dependent?

Back

Two events are dependent if the occurrence of one event affects the probability of the other event occurring.
