1. Data Recording and Analysis
Tables
Tables are the most basic form of numerical information. If
data in a table has not been summarised i.e. is the original data
collected, this is called raw data. At a glance tables demonstrate
experimental information e.g number of participants, conditions
and measurements taken etc.
Bar Charts
Used when experimental research demonstrates a difference
between sets of scores. A bar chart is a clear way of presenting
such data.
****************************************************
Find the data table that can be used to draw a bar chart.
Draw the bar chart on graph paper and stick both in your notes beneath
the above description

Line Graphs and Histograms
Counted data can be represented as a histogram or line graph
(frequency distribution curve). These demonstrate ranges in
data. The scores are laid out along the horizontal axis, with the
number of times a score occurred in each group along the
vertical axis.

Find the data table that can be used to draw a line graph or histogram.
Draw a line graph or histogram on graph paper and stick both in your
notes beneath the above description.

2. Data Curve
Measurements taken from the same person/people at several
points over time can be represented graphically as data curves.
****************************************************
Find the data table that can be used to draw a data curve.
Draw the data curve on graph paper and stick both in your notes beneath
the above description
****************************************************
Overlapping Curve
Overlapping data curves on one graph can be used to show
comparisons. At a glance you can see the effect the IV has had
on the DV over time.
****************************************************
Find the data table that can be used to draw overlapping curves.
Draw the graph on graph paper and stick both in your notes beneath the
above description.

Pie Charts
Give a visual impression of different proportions various groups
of people share. Segments represent percentages of a whole.
Scattergrams
Look back to your completed exercise on correlation for
examples and description.
