What is a right-skewed distribution?

Back

A right-skewed distribution is one where the tail on the right side is longer or fatter than the left side. This indicates that most of the data points are concentrated on the left, with fewer high values on the right.

What is a left-skewed distribution?

Back

A left-skewed distribution is one where the tail on the left side is longer or fatter than the right side. This indicates that most of the data points are concentrated on the right, with fewer low values on the left.

Front

What does it mean for a distribution to be approximately symmetrical?

Back

An approximately symmetrical distribution has a balanced shape where the left and right sides are mirror images of each other, indicating that the data is evenly distributed around the mean.

What is the factored form of a polynomial?

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce based on its domain.

Front

What is the significance of skewness in data distribution?

Back

Skewness indicates the direction and degree of asymmetry in a data distribution, which helps in understanding the nature of the data and its potential outliers.

Front

How do you determine the range of a graph?

Back

To determine the range of a graph, identify the lowest and highest y-values that the graph reaches.

Front

What is the difference between a left-tailed and right-tailed distribution?

Back

A left-tailed distribution has a longer tail on the left side, while a right-tailed distribution has a longer tail on the right side.

Front

What does it mean for a polynomial to have a double root?

Back

A double root occurs when a polynomial has a factor that is squared, indicating that the graph touches the x-axis at that root but does not cross it.
