7th 7-4 Probability Models

Front

What is a box plot?

Back

A box plot is a graphical representation of a dataset that shows its minimum, first quartile (Q1), median, third quartile (Q3), and maximum values. It helps visualize the distribution and variability of the data.

Front

What does IQR stand for and what does it represent?

Back

IQR stands for Interquartile Range. It represents the range of the middle 50% of a dataset, calculated as Q3 - Q1. It is a measure of statistical dispersion.

Front

How do you determine which class has more varied scores using IQR?

Back

Compare the IQRs of the two classes. The class with the larger IQR has more varied scores.

Front

What is a probability model?

Back

A probability model is a mathematical representation that describes the likelihood of different outcomes in a random experiment.

Front

How do you calculate the probability of an event?

Back

The probability of an event is calculated as the number of favorable outcomes divided by the total number of possible outcomes.

Front

What is the probability of spinning a number on a spinner?

Back

To find the probability of spinning a number, count the number of sections with numbers and divide by the total number of sections on the spinner.

Front

What does P(Blue) represent in probability?

Back

P(Blue) represents the probability of randomly selecting a blue marble from a box containing different colored marbles.

Front

How do you find the relative frequency of an event?

Back

Relative frequency is found by dividing the number of times an event occurs by the total number of trials.

Front

What is the formula for calculating percentage probability?

Back

Percentage probability = (Probability of the event) x 100%.

Front

What is the significance of conducting a survey in probability?

Back

Surveys help gather data to estimate probabilities and understand preferences or behaviors in a population.
