Divide the population area into sections (or clusters).
Then randomly select some of those clusters. Now
choose all members from selected clusters.

Cluster Sampling
,No data value is repeated.

No Mode
A bar graph for qualitative data, with the bars arranged in
descending order according to frequencies.
Give this one a try later!
Pareto Chart
A plot of paired (x, y) quantitative data with a horizontal x-axis and a vertical y-axis.
Used to determine whether there is a relationship between the two variables.

Scatterplot
What do each of these variance notations stand for? s, s^2, o, o^2

, s = sample standard deviation
s^2 = sample variance
o = population standard deviation
o^2 = population variance
Shows how a data set is partitioned among all of several categories (or classes) by
listing all of the categories along with the number (frequency) of data values in each
of them.

Frequency Distribution (or Frequency Table)
involves data that can be arranged in order and
the difference between any two data values is
meaningful. However, there is no natural zero
starting point (where none of the quantity is
present).

Interval level of measurement
Is the difference between two consecutive lower class limits or two consecutive lower
class boundaries.
