How to Present Data.
There are a number of different
ways of presenting data.
Presenting data means showing the results of an
experiment in a way which can be easily understood.
The way you chose to present your data
will depend on the type of variables in your experiment.
The lowest to the highest value of
your data is called its range.
You can calculate the average value of your data by adding up all
the values and dividing the total by the number of measurements.
For example, if you had made 8
measurements and your values
were 4,3,5,6,3,4,2 and 5, then the range would be from 2 to 6
and the average would be
(4 + 3 +5 + 6 + 3 + 4 +2 + 5) ÷ 8 = 4.
This type of average is called the mean.
The data below has been presented in the form of a table.
|Voltage / Volts||Current / Amps||Resistance / Ohms|
