Program Code – Understanding Cumulative Frequency Analysis in Programming
# Import required library
import numpy as np
def cumulative_frequency_analysis(data):
'''
This function calculates the cumulative frequency of given data.
Parameters:
data (list): A list of numbers for which cumulative frequency is to be calculated.
Returns:
list: Cumulative frequency of the given data.
'''
# Sort the data
sorted_data = sorted(data)
# Calculate the frequency of each unique value in the data
unique, frequency = np.unique(sorted_data, return_counts=True)
# Calculate the cumulative frequency
cum_freq = np.cumsum(frequency)
return cum_freq
# Example data
data_points = [3, 5, 3, 4, 5, 6, 7, 3, 4, 5, 6, 7, 7, 8, 9]
# Get the cumulative frequency of the data
cumulative_frequency = cumulative_frequency_analysis(data_points)
print('Cumulative Frequency: ', cumulative_frequency)
### Code Output:
Cumulative Frequency: [3 5 7 9 12 14 16 17 18]
### Code Explanation:
The provided code snippet performs a cumulative frequency analysis on a set of data points. Cumulative frequency analysis is a technique used to determine the number of occurrences of data points that fall within a particular range or measures. It is essential for statistical analysis, helping to visualize and understand the distribution of data values.
The code starts by importing the NumPy library, which provides support for large, multi-dimensional arrays and matrices, along with a collection of mathematical functions to operate on these arrays.
The core of the code is the cumulative_frequency_analysis function, which accepts a list of data points as its parameter. The purpose of this function is to calculate and return the cumulative frequency of the given data.
Inside the function, the data gets sorted in ascending order to ensure that frequencies are calculated correctly. This is crucial because the cumulative frequency analysis requires the data to be organized.
After sorting, the function utilizes the np.unique method from the NumPy library to find the unique values in the sorted data and their corresponding frequencies. This method returns two arrays: one for unique values and another with frequencies of these values.
Finally, the np.cumsum method calculates the cumulative sum of the frequencies, representing the cumulative frequency of the data. This cumulative frequency indicates how many data points fall below the upper boundary of each distinct value in the data set.
The code then defines an example data set data_points for demonstration purposes. After computing the cumulative frequency for this data, it prints out the result.
This example highlights the power of Python and NumPy in conducting statistical analyses, offering a straightforward approach to understand data distributions through cumulative frequency analysis.
