What is the maximum of a data set?

Back

The maximum of a data set is the largest value in that set.

Front

Describe the shape of a distribution that is skewed right.

Back

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

Front

True or False: The Mean and the Standard Deviation are strongly affected by outliers.

Back

TRUE

Front

What does it mean if the mean is less than the median in a data set?

Back

It indicates that the data set is skewed left, meaning there are lower values that pull the mean down.

Front

True or False: 50% of the girls have a height that is greater or equal to 66 inches if the median height is 66 inches.

Back

FALSE

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 certain ranges.

Front

What does it mean if a distribution is symmetric?

Back

A symmetric distribution has a balanced shape, where the left and right sides are mirror images of each other.

Front

What is the relationship between mean and median in a skewed right distribution?

Back

In a skewed right distribution, the mean is typically greater than the median.

Front

Define outlier in a data set.

Back

An outlier is a data point that is significantly different from the other observations in the data set, often lying outside the overall pattern.

Front

What is the effect of outliers on the mean?

Back

Outliers can significantly increase or decrease the mean, making it less representative of the data set.
