Q1 : What is Bar Graph ?

Ans :  In bar graph, Bars of uniform width are drawn with various heights. The height of bar represents the frequency of the corresponding  observation.

✯ Bar Graphs are used to represent unclassified frequency distributions.

✯ Frequency of a value of a variable is represented by a bar, whose length is equal to the frequency.

✯ The breadth of the bar is arbitrary and the breadth of all the bars are equal. The bar may or may not touch each other.

Q2 : What is line graph ?

Ans :  A line graph is useful for displaying data  that changes continuously over time.

✯ Another name for a line graph is a line chart.
