Normal Distribution and Z Score

Flashcards covering Normal Distribution concepts, forms of Kurtosis, and the Z Score definition and formula.

Normal Distribution

A common statistical distribution often visualized as a bell-shaped curve.

Leptokurtic

A form of kurtosis characterized by a distribution with a sharp peak and heavy tails.

Mesokurtic

A form of kurtosis that represents a normal distribution, characterized by an intermediate peak and tails.

Platykurtic

A form of kurtosis characterized by a distribution with a flat peak and light tails.

Kurtosis

A statistical measure describing the shape of a probability distribution's peaks and tails, relative to a normal distribution.

Z Score

A statistical measure used to determine how many standard deviations a raw score (x) is from the mean (x
T) of a dataset, calculated by the formula Z = (x – x
T)/SD.
