Input the required data values separated by commas into the following calculator and calculate the mean, median, mode and range in seconds.
The calculator determines the mean, median, mode and range for the given data set along with the sum, minimum, maximum, range, and count. With the help of a mean, median, mode, range calculator, you can efficiently analyze data sets and compute key statistical values to gain valuable insights in no time.
In statistics, a central tendency (or measure of central tendency) is said to be a central or typical value for a probability distribution. And, the most common measures of central tendency are said to be the arithmetic mean, the median, and the mode. In simple words, the ‘mean’ is said to be the average of all the data in a set. Mathematically, the ‘mean’ is a kind of average, which is found by dividing the sum of a set of numbers by the count of numbers in the data set. The median is referred to as the middle values in a given data set or it is a simple measure of central tendency, separating the upper half of a data set from the lower half. The definition of mode states, it is the value that occurs most frequently in a data set. It is used to show the information related to the random variables and populations. Read more! And learn how to find the mean median mode range.
Go through the following steps to find the mean:
Where;
Example:
Find the mean for a data set, X = 2, 3, 4, 5, 6.
Solution:
Sum = \(\sum X\) = 2 + 3 + 4+ 5+ 6 = 20
Total Numer of Values = N = 5
\(\ μ =\dfrac{∑X}{N}\)
\(\ μ =\dfrac{20}{5}\)
μ = 4
Here are the steps:
To calculate the median, the following formula will be taken into account:
\(\mathrm{Med}(X) = \begin{cases} X[\frac{n+1}{2}] & \text{if n is odd} \\ \frac{X[\frac{n}{2}] + X[\frac{n}{2}+1]}{2} & \text{if n is even} \end{cases}\)
Let’s take a look at this data set to understand the concept, 1, 2, 3, 5, 7 – you can see that there are two numbers in front of the 3, and also the two numbers behind it. It shows that 3 is the number that is exactly in the middle of the data sample.
In the data set 1, 1, 4, 6, 6, 9 the median is 5. By taking the mean of even numbers 4 and 6 we have \((\dfrac{4+6}{2})=\ 5\).
So, it’s clear that the median in an even set of numbers doesn’t have to be a number in the data set itself.
Follow the below-mentioned steps:
Example:
Let's suppose you have a data sample as 3, 7, 5, 13, 20, 23, 39, 23, 40, 23, 14, 12, 56, 23, 29 Now, find the Mode:
Solution:
Arrange these numbers: 3, 5, 7, 12, 13, 14, 20, 23, 23, 23, 23, 29, 39, 40, 56 By ordering, this becomes easy to see which numbers appear most often. In this example, the mode of numbers is 23.
So, what about More Than One Mode: Sometimes we can have more than one mode.
Example:
{1, 3, 3, 3, 4, 4, 6, 6, 6, 9}
Solution:
Here you can see that 3 appears three times, as does 6. So, it means there are two modes i:e 3 and 6 Remember that:
Mathematically, the range of a data sets is said to be the difference between the highest/largest and smallest/lowest values in the data set. The range is a measure of variability.
