Obtaining Differential and Cumulative Distribution Frequency

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.

hello all.glad to be here!

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.
 

FAQ: Obtaining Differential and Cumulative Distribution Frequency

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.
