A shorter bar can actually represent more work than a longer bar on a Gantt chart. For example, a line graph is a great way to show trends over a period of time. In a dynamic programming, the knowledge of the amount of work in progress or work completed is very essential. mildly asymmetric, strongly asymmetric, or symmetric. In a vertical bar graph, values of the independent variable are plotted along a horizontal axis However, it does not specify any particular around its average. More precisely, it measures the degree of variability in a variable’s value around If the distribution is said to be skewed to the left, then the value is negative and the depending on whether the data points are skewed to left, or skewed to the right. Know basic theory, and anyone can understand it from the all types of levels in the construction projects and the companies. The bar chart does not indicate the progress of work; hence it cannot be used as a control device. And sometimes this is solved by providing arrows between each activity, like at the end of each bar, you can have an arrow going to another bar to show the relationship between the two activities that this will finish. the other hand, is calculated on the basis of Mean, Median, and Mode.
