Standard Normal Distribution Flashcards
A continuous, symmetric, bell-shaped distribution of a variable.
Normal Distribution
Distribution is bell shaped.
Normal Distribution
The mean, median, and mode are equal and are located at the center of the distribution.
Normal Distribution
It is unimodal and continuous.
Normal Distribution
First derived by Abraham De Moivre (1667-1754), with contributions of the German mathematician, physicist and astronomer Carl Friedrich Gauss.
Normal Distribution
Normal Distribution also known as?
Gaussian Curve
It is a graphical representation of the probability that the data collected distributes itself normally.
Gaussian curve or Normal Distribution
Asymmetrical or abnormal distribution of data in relation to the mean.

[3] types of Distribution
- Symmetrical Distribution
- Positively Skewed Distribution
- Negatively Skewed Distribution
Data values are evenly distributed on both sides of the mean.
[types of distribution]
Symmetrical Distribution
The distribution that is unimodal and the mean, median, and mode are similar and at the distribution’s center.
[types of distribution]
Symmetrical Distribution
Most of the values in the data fall to the left of the mean and group at the lower end of the distribution; tail is to the right.
[types of distribution]
Positively Skewed Distribution
The mean is to the right of the median, and the mode is to the left of the median.
[types of distribution]
Positively Skewed Distribution
The mass of the data values falls to the right of the mean and group at the upper end of the distribution; tail is to the left.
[types of distribution]
Negatively Skewed Distribution
The mean is to the left of the median, and the mode is to the right of the median.
