What is cumolative frequency curve?
A cumulative frequency curve is a graph that shows the cumulative frequency of a data set. This type of graph can present data, such as medians and quartiles. Another name for this curve is an Ogive.

Usefulness of cumulative frequency curve?
It will show you whether it is a constant rate or if it speeds up or slows down.
What is the first thing you need to do to create a box and whisker plot of a data set?
You need to do a cumulative frequency curve
How do you get a cumulative percentage having a mass percentage?
You cannot. The two are different things!
What is meant by mass curve in hydro power plant?
Mass curve is a plot of the cumulative inflows and outflows versus time used for calculating the storage capacity of a hydro unit.

What is another name of cimulative curve?
Another name for a cumulative curve is a cumulative frequency curve. This type of graph represents the cumulative total of frequencies for a given dataset, showing how many observations fall below a particular value. It is often used in statistics to visualize the distribution of data.
What is utility of cumulative frequency curve?
The main utility of a cumulative frequency curve is to show the distribution of the data points and its skew. It can be used to find the median, the upper and lower quartiles, and the range of the data.
Can the slope of a lorenz curve be greater than 1?
No, the slope of a Lorenz curve cannot be greater than 1. The Lorenz curve represents the cumulative distribution of income or wealth, and its slope reflects the proportion of total income earned by a certain percentage of the population. Since the curve plots cumulative shares of income against cumulative shares of the population, the maximum slope occurs at the point where the entire population earns all the income, which results in a slope of 1.
How do you plot a lorenz curve?
To plot a Lorenz curve, first, gather the data for the variable of interest (e.g., income) and sort it in ascending order. Next, calculate the cumulative percentages of the total population and the cumulative percentages of the total income, plotting these values on a graph where the x-axis represents the cumulative population percentage and the y-axis represents the cumulative income percentage. The resulting curve illustrates income distribution, with the line of equality (45-degree line) serving as a reference for perfect equality. The further the Lorenz curve is from this line, the greater the inequality in the distribution.
What is the difference between a cummulative frequency graph and a cumulative frequency polygon?
A cumulative frequency polygon has straight lines connecting the points. A normal cumulative frequency diagram uses a smooth curve to join the points.

Cumulative Mass Function
How do you draw a cumulative frequency frequency polygon and a frequency curve?
To draw a cumulative frequency frequency polygon, plot cumulative frequency on the y-axis and the upper boundary of each class interval on the x-axis. Then connect the points with straight line segments, starting from the x-axis at 0 cumulative frequency. For a frequency curve, plot the midpoint of each class interval on the x-axis and the frequency on the y-axis. Then connect the points smoothly with a curve to show the distribution of data.
Usefulness of cumulative frequency curve?
It will show you whether it is a constant rate or if it speeds up or slows down.
Usefullness of ogive curve?
In statistics, the ogive curve is an approximation to the cumulative distribution function. It can be used to obtain various percentiles quickly as well as to derive the probability density function.
