What is relative frequency?

Back

Relative frequency is the ratio of the number of times an event occurs to the total number of trials or observations. It is often expressed as a decimal or percentage.

Front

How do you calculate relative frequency?

Back

Relative frequency = (Number of favorable outcomes) / (Total number of outcomes).

Front

What does a skewed right distribution indicate?

Back

A skewed right distribution indicates that the majority of the data points are concentrated on the left side, with a long tail extending to the right.

Front

What is a box plot?

Back

A box plot is a graphical representation of data that shows the distribution's minimum, first quartile, median, third quartile, and maximum.

Front

What does the minimum value in a box plot represent?

Back

The minimum value in a box plot represents the smallest data point in the dataset.

Front

How do you interpret the shape of a distribution?

Back

The shape of a distribution can indicate the nature of the data, such as whether it is symmetrical, skewed, or uniform.

Front

What is the purpose of a relative frequency table?

Back

A relative frequency table summarizes the relative frequencies of different categories or outcomes in a dataset.

Front

How do you find the percentage of a specific category in a dataset?

Back

Percentage = (Number of items in the category / Total number of items) x 100.

Front

What does it mean if a distribution is uniform?

Back

A uniform distribution means that all outcomes are equally likely, and the frequencies of each category are approximately the same.

Front

What is the median in a dataset?

Back

The median is the middle value when the data points are arranged in ascending order.
