Detailed explanation-1: -We usually us a bar chart for discontinuous variation data: We usually us a line graph for continuous variation data: This means that living things will naturally show variation (they will be different to each other).
Detailed explanation-2: -There is no range of data. What chart do you use to plot discontinuous variation? You use a bar chart with gaps between the bars. This is because there is no range of data.
Detailed explanation-3: -A bar graph is used to show comparison between different categories. It is used to represent discontinuous, ungrouped data. On the other hand a histogram is used to represent continuous, grouped data.
Detailed explanation-4: -Discontinuous variation refers to things like eye colour or blood group, which have a limited number of possible values. In other words, a person’s blood can be A, B, AB or O, but it can’t be anything in between.
Detailed explanation-5: -The six types of bar graphs are vertical, horizontal, double, multiple, stacked, and bar-line bar graphs.
