What is another name for normal distribution?

• Gaussian distribution

• Poisson distribution

What is the total area in the distribution under the curve?

• 0

• 1

It characterize the spread or range of a normal distribution/data set?

• Sample Mean

• Population Mean

• Standard Deviation

• Sample Size

Which value is found at the center of the normal curve?

• Mean

• Median

• Mode

• All of the Above

The normal distribution is a bell-shaped curve.

• True

• False

In a normal distribution, the curve is symmetrical along the mean.

• True

• False

What can you assume if the graph of a distribution is bell-shaped?

• The distribution is normal.

• The distribution is continuous.

• The distribution is bimodal.

• The distribution is not skewed.

How will you interpret normal distributions with higher standard deviations?

• They have smaller area.

• They have a larger mean.

• They are more spread out.

• They are more compact.

What does the statement “a normal curve is continuous” imply?

• It extends indefinitely to the left.

• It extends indefinitely to the right.

• It extends in both directions, but only up to a certain point.

• It extends indefinitely in both directions.

Approximately 68.26 % of the data fall within two standard deviation from the mean.

• TRUE

• FALSE
