Front

What is the formula to find the period of a sine or cosine graph?

Back

The period can be found using the formula: 2π/B, where B is the frequency.

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 there are a few high values that pull the mean to the right.

Front

What is the amplitude of a sine or cosine graph?

Back

The amplitude is the maximum distance from the midline to the peak of the graph. For example, if the maximum value is 2 and the minimum is -2, the amplitude is 2.

Front

What is the exact value for a given trigonometric function?

Back

The exact value refers to the precise value of a trigonometric function at a specific angle, often expressed in terms of square roots or fractions.

Front

How do you determine the period of a trigonometric function?

Back

The period can be determined by identifying the distance between two consecutive peaks or troughs in the graph.

Front

What is the definition of frequency in relation to sine and cosine graphs?

Back

Frequency is the number of cycles a wave completes in a unit of time, and it is the reciprocal of the period.

Front

What is the relationship between amplitude and the height of a wave?

Back

The amplitude is half the distance between the maximum and minimum values of the wave.

Front

What does it mean for a distribution to be symmetric?

Back

A symmetric distribution has a mirror image on either side of the center, meaning the left and right sides are balanced.

Front

What is the difference between unimodal and bimodal distributions?

Back

A unimodal distribution has one peak, while a bimodal distribution has two distinct peaks.

Front

How can you identify a skewed left distribution?

Back

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