# Obtaining Differential and Cumulative Distribution Frequency

• pid3control
In summary, the purpose of obtaining differential and cumulative distribution frequency is to analyze and visualize the distribution of a set of data. Differential frequency is calculated by counting the number of times a particular value appears in a set of data, while cumulative frequency represents the total number of data points that fall below or equal to a certain value. To obtain a differential frequency graph, the data is organized into a frequency table and then plotted on a graph. The main difference between differential and cumulative frequency is that differential frequency represents occurrences of a particular value, while cumulative frequency represents total values below or equal to a certain value.

please in the attached document, column 5 and 6 which represents the differential and cumulative frequency distributions were obtained using equations (5) and (6). I'll be mighty grateful if anyone can give me a step by step breakdown of how it was done?? Many thanks
pls note: x is the mass fraction of the Rejection g (column 2)
D is the arithmetic mean of the nominal size

Sorry, but I find that impossible to read. Apparently, even enlarging the screen does not enlarge your upload.

## 1. What is the purpose of obtaining differential and cumulative distribution frequency?

The purpose of obtaining differential and cumulative distribution frequency is to analyze and visualize the distribution of a set of data. This allows researchers to better understand the patterns and trends within the data, and make informed decisions based on the information gathered.

## 2. How is differential frequency calculated?

Differential frequency is calculated by counting the number of times a particular value appears in a set of data. This value is then divided by the total number of data points in the set, and the result is expressed as a percentage or decimal.

## 3. What does cumulative frequency represent?

Cumulative frequency represents the total number of data points that fall below or equal to a certain value in a data set. It is used to analyze the overall distribution of the data and identify any outliers or patterns.

## 4. How do you obtain a differential frequency graph?

To obtain a differential frequency graph, the data is first organized into a frequency table that lists the values and their corresponding frequencies. The values are then plotted on the x-axis and their corresponding frequencies on the y-axis. The resulting graph shows the distribution of the data.

## 5. What is the difference between differential and cumulative frequency?

The main difference between differential and cumulative frequency is that differential frequency represents the number of occurrences of a particular value in a data set, while cumulative frequency represents the total number of values that fall below or equal to a certain value in the data set.
