Question

Hello friends:-)Good morning

Can you help me please

Define
-Bar graph
-Line graph
-Histogram

Difference between
-Bar graph and Line graph
​

Answer 1

• Bargraph is a chart which uses bars to show comparisons between categories of data.
• Line graphics a graph in which points representing values of a variable for suitable values of an independent variable are connected by a broken line.
• Histogram is a diagram considering of rectangle whose area is proportional to the frequency of a variable and whose width is equal to the class interval.
• Bargraphs use rectangular blocks to represent data whereas line graph uses lines to represent data

Answer 2

bar graph =such a graph usually consists of a vertical rectangles called columns o r bars of different Heights but the same width. the height of a bar on suitable scale indicates the magnitude of the corresponding entry horizontal bars of different length can also be used the gap between the bars must be uniform

line graph=which displays information as a series of data points called 'markers' connected by straight line segments. It is a basic type of chart common in many fields

histogram=A histogram is a display of statistical information that uses rectangles to show the frequency of data items in successive numerical intervals of equal size. In the most common form of histogram, the independent variable is plotted along the horizontal axis and the dependent variable is plotted along the vertical axis. The data appears as colored or shaded rectangles of variable area.
