Statistics Calculator: Unveiling Mean, Median, and Mode 📊

Statistics play a pivotal role in understanding data patterns and drawing meaningful conclusions. In this context, we’ll delve into the concepts of mean, median, and mode—three essential measures of central tendency.

Mean: The Average Value

• Definition: The mean represents the average value of a dataset.
• Calculation: Add up all the data values and divide by the total count of values.
• Formula: The mean \(x̄\) of a dataset is the sum of all data divided by the count \(n\):
• \(mean = x̄ = \frac{∑_{i=1}^n x_i}{n}\)

Median: The Middle Value

• Definition: The median is the data value that separates the upper half from the lower half of a dataset.
• Procedure:
  1. Arrange data values from lowest to highest.
  2. Locate the central value.
  3. If there are 2 values in the middle, take their average.
• Example:
  • For the dataset: 1, 1, 2, 5, 6, 6, 9
  • The median is 5.
  • For the dataset: 1, 1, 2, 6, 6, 9
  • The median is 4 (average of 2 and 6).

Mode: The Most Frequent Value

• Definition: The mode is the number in a dataset that occurs most frequently.
• Procedure:
  • Count how many times each number occurs in the data set.
  • The mode is the number with the highest tally.
  • It’s okay if there is more than one mode.
  • If all numbers occur the same number of times, there is no mode.
