Notes:
There are two main types of Distribution we are concerned with in statistics:
Frequency Distributions:
A graph representing the frequency of each outcome occurring.
Probability Distributions:
A graph that provides the probability of each outcome occurring.
The most common distribution shapes are:
Symmetric:
Bellshaped:
Skewed to the left:
Skewed to the right:
Uniform:
Cluster:
On a graph a cluster is when several data points lie close together. Typically this means that these data points have similar characteristics, which is also called things are homogeneous (Things which are very diverse or dissimilar are called heterogeneous)
Gap:
A gap is an interval which contains no data.
Peak:
A peak is the highest point of a data set.
