The mean is the sum of all values in a dataset divided by the total number of values. It represents the central tendency or typical value of a set of numbers.
Mean (μ) = Sum of values (x) / Number of values (N)
Example
For the input 1, 2, 3, the sum is 1 + 2 + 3 = 6. The number of values is 3. Therefore, the mean is 6 / 3 = 2.
Calculate
Explanation
The X-axis (horizontal axis) represents the index of each data point in the dataset. Each label on the X-axis corresponds to a specific data point, with the first data point shown as Data Point 1, the second as Data Point 2, and so on. This allows you to visually identify and compare individual data points.
The Y-axis (vertical axis) displays the value of each data point. The height of each bar on the chart corresponds to the value of that data point, making it easy to see the range and distribution of the dataset.
The Mean value is indicated by the horizontal dashed red line on the chart. This line helps you compare each data point with the average value of the dataset, providing a quick way to see which points are above or below the mean.
The Median value is shown by the horizontal dashed green line. The median represents the middle value of the dataset when it is ordered from lowest to highest. This line gives you a sense of the central tendency that is not skewed by extreme values.
The Mode value is marked by the horizontal dashed brown line. The mode is the most frequently occurring value in the dataset. This line indicates the value that appears most often, highlighting any common data points or peaks in the dataset.
