Learn how to calculate and compare the mean, median and mode of a set of data. See the difference between these measures of central tendency with examples, video lessons and practice questions.
- Mean median and mode are the three measures of central tendency. The mean is the value obtained by dividing the sum of the observations by the numb...
- Mean is calculated for ungrouped data using the formula as: Mean = Sum of observations/Number of observations In the case of grouped data, the me...
- For ungrouped data, the median can be calculated using the formulas given below: Median = (n + 1)/2th observation {when n is odd} Median = Averag...
- Mode is the most frequently observed value in the data set. For grouped data, mode = l + [(f_1 – f_0)/(2f_1 – f_0 – f_2)] × h
- The relationship between mean mode and median is given as: Mode = 3 Median – 2 Mean

Measures of central tendency are summary statistics that represent the center point or typical value of a dataset. Examples of these measures include the mean, median, and mode. These statistics indicate where most values in a distribution fall and are also referred to as the central location of a distribution. You can think of central tendency as ...
Most articles about the mean, median, and mode focus on how you calculate these measures of central tendency. I’ll certainly to that, but I’m going to start with a slightly different approach. My philosophy throughout my blog is to help you intuitively grasp statistics by focusing on concepts. Consequently, I’m going to start by illustrating the ce...
The mean is the arithmetic average, and it is probably the measure of central tendency that you are most familiar. Calculating the mean is very simple. You just add up all of the values and divide by the number of observations in your dataset. The calculation of the mean incorporates all values in the data. If you change any value, the mean changes...
The median is the middle value. It is the value that splits the dataset in half, making it a natural measure of central tendency. To find the median, order your data from smallest to largest, and then find the data point that has an equal number of values above it and below it. The method for locating the median varies slightly depending on whether...
The mode is the value that occurs the most frequently in your data set, making it a different type of measure of central tendency than the mean or median. To find the mode, sort the values in your dataset by numeric values or by categories. Then identify the value that occurs most often. On a bar chart, the mode is the highest bar. If the data have...
When you have a symmetrical distribution for continuous data, the mean, median, and mode are equal. In this case, analysts tend to use the mean because it includes all of the data in the calculations. However, if you have a skewed distribution, the median is often the best measure of central tendency. When you have ordinal data, the median or mode ...
Learn how to calculate and compare the mean, median, and mode as summary statistics that represent the center point or typical value of a dataset. See how these measures of central tendency differ in symmetric and skewed distributions, and how to choose the best one for your data.

Median: The median is the middle value of a data set, which separates the highest and lowest values equally. It is calculated by arranging the data set in order from lowest to highest and finding the value in the exact middle. Mode: The mode is the value that appears most frequently in a data set.
