What is the mean in a data set?

Back

The mean is the average of a set of numbers, calculated by adding all the values together and dividing by the number of values.

Front

What happens to the mean if a value greater than the current mean is added to the data set?

Back

The mean will increase.

Front

What is a histogram?

Back

A histogram is a graphical representation of the distribution of numerical data, showing the frequency of data points within specified ranges.

Front

What does it mean if a histogram is skewed right?

Back

A right-skewed histogram has a longer tail on the right side, indicating that there are a few high values that are pulling the mean to the right.

Front

What does it mean if a histogram is skewed left?

Back

A left-skewed histogram has a longer tail on the left side, indicating that there are a few low values that are pulling the mean to the left.

Front

What is normal distribution?

Back

Normal distribution is a probability distribution that is symmetrical and bell-shaped, where most of the observations cluster around the central peak.

Front

How do you find the median of a data set?

Back

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

Front

What is the mode of a data set?

Back

The mode is the value that appears most frequently in a data set.

Front

What is the range of a data set?

Back

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

Front

What is a sample in statistics?

Back
