calculate the mean, median, mode, range, variance, standard deviation, the quartiles, and the interquartile range for the visual band magnitude data. in matlab

To calculate the mean, median, mode, range, variance, standard deviation, quartiles, and the interquartile range for visual band magnitude data in MATLAB, you can use the built-in functions provided by the Statistics and Machine Learning Toolbox.

Here's an example code that demonstrates how to perform these calculations:

main.m
% Visual band magnitude data
data = [10, 15, 12, 17, 10, 20, 15, 10, 13, 15, 18, 12, 10];

% Mean
mean_value = mean(data);

% Median
median_value = median(data);

% Mode
mode_value = mode(data);

% Range
range_value = range(data);

% Variance
variance_value = var(data);

% Standard deviation
std_deviation = std(data);

% Quartiles
quartiles = quantile(data, [0.25, 0.5, 0.75]);

% Interquartile range
interquartile_range = quartiles(3) - quartiles(1);

In this code, the data variable represents the visual band magnitude data. You can replace it with your own dataset.

Each calculation is performed using a specific MATLAB function:

• mean – calculates the mean of the data.
• median – calculates the median of the data.
• mode – calculates the mode of the data. Note that MATLAB's mode function returns the most frequent value in the dataset, but it can also return multiple values if there are multiple modes.
• range – calculates the range of the data, which is the difference between the maximum and minimum values.
• var – calculates the variance of the data.
• std – calculates the standard deviation of the data.
• quantile – calculates the desired quartile(s) of the data. In the example code, we calculate the first quartile (25th percentile), median (50th percentile), and third quartile (75th percentile) by passing [0.25, 0.5, 0.75] as the second argument.
• interquartile_range – calculates the interquartile range as the difference between the third and first quartiles.

Feel free to modify the code according to your specific data and requirements.
