Mean, Median, and Mode calculations:
The mean, median, and mode are three commonly used measures of central tendency that provide insights into the central tendency and variability of a data set.
Mean (Average): The mean, also known as the average, is the sum of all the values in the dataset divided by the total number of values. It is a weighted average where heavier values have a greater impact on the mean.
Median: The median is the middle value in the dataset when arranged in order from smallest to largest. If there are an odd number of values, the median is the average of the two middle values.
Mode: The mode is the value that appears most frequently in the dataset. It is the most common value in the data set.
Examples:
If we have the following dataset: 5, 10, 15, 20, 25, 30, the mean would be (15 + 20 + 25 + 30) / 5 = 20.
If the dataset is {5, 10, 15}, the median would be 15, as it is the middle value when arranged in order.
If the dataset has the following values: 5, 5, 5, 10, 10, 15, 20, the mode would be 5, as it appears most frequently.
Understanding the mean, median, and mode is essential for interpreting data sets and making meaningful conclusions about their central tendency and variability
