6th Statistics and Probability Review

Front

What is the RANGE in statistics?

Back

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

Front

How do you calculate the MEAN of a set of numbers?

Back

To find the MEAN, add all the numbers together and then divide by the total count of numbers.

Front

What is a SAMPLE SPACE in probability?

Back

The SAMPLE SPACE is the set of all possible outcomes of a probability experiment.

Front

How do you find the PROBABILITY of an event?

Back

PROBABILITY is found by dividing the number of favorable outcomes by the total number of possible outcomes.

Front

What is THEORETICAL PROBABILITY?

Back

THEORETICAL PROBABILITY is the likelihood of an event occurring based on all possible outcomes.

Front

What is the formula for calculating RANGE?

Back

RANGE = Highest value - Lowest value.

Front

What is the difference between experimental and theoretical probability?

Back

Experimental probability is based on actual experiments, while theoretical probability is based on expected outcomes.

Front

If a bag contains 3 red marbles and 7 total marbles, what is the probability of picking a red marble?

Back

The probability is 3/7.

Front

What does it mean if an event is certain?

Back

If an event is certain, its probability is 1.

Front

What does it mean if an event is impossible?

Back

If an event is impossible, its probability is 0.
