GRAPHING AND GRAPHICAL ANALYSIS
Laboratory report: Graphing and Graphical analysis
Objectives
This laboratory exercise is conducted so as to achieve the following objectives:
1. Understand the different types of graphs
2. Differentiate the linear relationship, power and exponential relationship from the
shape of the curves
3. Plotting and determination of the equation of the curves
Background information
In every experiment set up, the main goal is to determine the relationship between the
experiment quantities and how they depend on each other. Through this, a predetermined
constant is verified or improved. In the below lab exercises, there is the plotting and analysis
of graphs. The graphs plotted are used to determine the relationship between pairs. The
graphs can help one calculate one quantity if given the other.
Procedure
From the given data, graphs were plotted for each data separately. The most suitable
scale was determined and the marks for the values were made on the plotting material. For
each pair, points were made and then the same points connected thus plotting a graph for the
pair. From the shape of the various curves i.e. the appearance, the pairs’ relationship could be
predicted. The values to be used to calculate the gradient were determined from the best fit
line. The dashed lines were then drawn to show the steep and the error bars were used in the
determination of shallow lines. The y intercept together with the gradient for the two lines
were calculated. The figures were helpful in calculation and determination of uncertainties in
the gradient and the y intercept.
