Normal Curve

Front

What is the Normal Curve?

Back

The Normal Curve, also known as the Gaussian distribution, is a bell-shaped curve that represents the distribution of a set of data where most values cluster around a central peak and probabilities for values further away from the mean taper off equally in both directions.

Front

What percentage of data falls within one standard deviation of the mean in a Normal Distribution?

Back

68% of the data falls within one standard deviation of the mean in a Normal Distribution.

Front

What percentage of data falls within two standard deviations of the mean in a Normal Distribution?

Back

95% of the data falls within two standard deviations of the mean in a Normal Distribution.

Front

What percentage of data falls within three standard deviations of the mean in a Normal Distribution?

Back

99.7% of the data falls within three standard deviations of the mean in a Normal Distribution.

Front

What is the mean in a Normal Curve?

Back

The mean is the average of all data points and is located at the center of the Normal Curve.

Front

What is the median in a Normal Curve?

Back

The median is the middle value of the data set and is equal to the mean in a Normal Distribution.

Front

What is the mode in a Normal Curve?

Back

The mode is the value that appears most frequently in a data set and is also located at the peak of the Normal Curve.

Front

What does it mean for a distribution to be symmetrical?

Back

A symmetrical distribution means that the left side of the curve is a mirror image of the right side, indicating that data is evenly distributed around the mean.

Front

What is a characteristic of a Normal Distribution?

Back

A Normal Distribution is bell-shaped, symmetrical, and continuous.

Front

What is NOT a characteristic of Normal Distribution?

Back

Randomness is NOT a characteristic of Normal Distribution; it is structured and predictable.
