Frequency distribution of classes data

I have a timetable with values and I need to calculate the frequency distribution in classeswith step of 0.How can I fill the classes until 100 (even with zeros I expect to have higher values).

Hi @Ancalagon8,

I understand that you have a dataset represented as a timetable and you want to analyze the frequency distribution of these values by categorizing them into discrete classes from 0 to 100. Here is an example of how to approach this:

1. Prepare your data: Ensure your timetable values are in a vector format that MATLAB can process.
2. Define the classes: Since you want classes from 0 to 100, you will define these classes explicitly.
3. Use the 'histcounts' function: This function will help you calculate the frequency distribution.

% Assume 'data' is your vector containing the timetable values
data = [add_data_here]; % Replace with your actual data

% Define the edges of the classes (bins)
edges = 0:1:100; % Classes from 0 to 100 with step of 1

% Calculate the frequency distribution
[freq, edges] = histcounts(data, edges);

% Display the frequency distribution
disp('Class Edges:');
disp(edges);
disp('Frequencies:');
disp(freq);

% Plot the histogram
figure;
histogram(data, edges);
xlabel('Class');
ylabel('Frequency');
title('Frequency Distribution');

Frequency distribution for a randomly generated set of data is shown below:

Kindly refer to the following documentation for more information on the 'histcounts' function:

I hope this helps!
