Frequency Distribution

A frequency distribution is an organized tabulation of the number of individuals in each category on the scale of measurement.

Symmetrical Distribution
In a symmetrical distribution, it is possible to draw a vertical line through the middle so that one side of the distribution is a mirror image of the other.
Skewed Distribution
In a skewed distribution, the scores tend to pile up toward one end of the scale and taper off gradually at the other end.
Tail
The section where the scores taper off toward one end of a distribution is called the tail of the distribution.
Positively Skewed / Negatively Skewed
A skewed distribution with the tail on the right-hand side is positively skewed because the tail points toward the positive ( above zero ) end of the X-axis. If the tail points to the left, the distribution is negatively skewed.
Rank ( Percentile Rank )
The rank or percentile rank of a particular score is defined as the percentage of individuals in the distribution with scores equal to or less than the particular value.
Percentile
When a score is identified by its percentile rank, the score is called a percentile.
