Question

How are graphs useful in analysis ?
Explain with a suitable example. ​

Answer 1

$\huge\underline\frak{\fbox{AnSwEr :-}}$

Graphs are useful tools that can elucidate relationships between two physical parameters. In Analytical chemistry, graphs are plotted when the relation between two properties of matter under study have to be deduced.

For example, the relation between temperature and volume of a given amount of gas can be studied by plotting a graph of (V) versus(T).

Hope it helps you...

Explanation:

A graph is a diagram that is meant to represent data and to portray a relationship. Analysing graphs is useful for determining the general trend, relating the results of an experiment to the hypothesis and for formulating hypotheses for future experiments. When analysing graphs, it is important to determine what the graph is displaying and why such information is pertinent to the experiment or to the context of the question. More than one type of graph can be used to represent a single set of data.

Distinguish between the various types of graphs. The main types of graphs are picture graphs, bar graphs, line graphs and scatter plots. A picture graph uses pictures to represent values. Bar graphs use either vertical or horizontal bars to represent the values. Line graphs use lines to represent the values. Scatter plots represent the data with points, and then a best-fit line is drawn through some of the points.

EXAMPLES:

Graphs are used for,

              (1)Misleading scales

              (2)Computer fits

              (3)Guiding experimentation

              (4)Transformation of variables

              (5)Changing the distribution
