A way of representing activities and
dependencies involved in a complex project. There
are several versions of Activity Network Diagram,
the main types being PERT and CPM.
| Box
Plots (Box and Whisker Plots) |
|
Box Plots are used to represent
relatively small data sets. The standard format
of a box is shown below:
The outliers are points that are more
than 1.5 times the interquartile range above the
third quartile or below the first quartile. The
whiskers extend to the largest, and smallest,
data values that are not outliers.
A tally sheet that is used to collect
data . It is a simple method that can be used
with a minimum of instruction:
A Pareto Chart would often be a useful
next step for analyzing the results.

Criteria Method |

See Prioritization Matrices
Critical Path Method. Essentially the
same as PERT, although there are some technical
differences.
A graphical tool for helping to chose
between several courses of action. The tree starts
with the decision that has to be made. The branches
are then formed from the future decisions that
the initial decision will leads to, or to the
possible outcomes from the decisions:
A diagram, or table, that shows the number
of observations falling into each of several ranges
of values. A histogram is a common method for
representing a frequency distribution.
A chart showing the work breakdown against
time. The vertical axis shows the activities and
the horizontal axis the time (in days, weeks,
months etc.)
A graphical method that represents the
distribution of values in a data set. The data
values are grouped into ranges and shown as bars
on a histogram:
