Back

A symmetric distribution is one where the left and right sides of the distribution are mirror images of each other.

Front

What is the primary characteristic of a skewed left distribution?

Back

A skewed left distribution has a longer tail on the left side, indicating that most data points are concentrated on the right.

Front

What does it mean if a distribution is skewed right?

Back

A skewed right distribution has a longer tail on the right side, indicating that most data points are concentrated on the left.

Front

What is the definition of a data distribution?

Back

A data distribution represents how data points or scores are spread out across different values.

Front

What is the shape of a normal distribution?

Back

A normal distribution is bell-shaped and symmetric around the mean.

Front

What is the significance of the mean in a symmetric distribution?

Back

In a symmetric distribution, the mean, median, and mode are all equal.

Front

How can you identify a skewed distribution visually?

Back

A skewed distribution can be identified by its asymmetrical shape, where one tail is longer than the other.

Front

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

Back

In a skewed left distribution, the mean is typically less than the median.

Front

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

Back

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

Front

What is a uniform distribution?

Back

A uniform distribution is one where all outcomes are equally likely, resulting in a flat shape.
