The QUARTILE Function[1]is categorized under ExcelStatistical functions. The function will return the quartile of a given data set. As afinancial analyst, QUARTILE can be used to find out, for example, a specific percentage of incomes in a population. The function is very useful in revenue an...
The lower quartile (sometimes called Q1) is the number dividing the first and second quartile. The lower quartile formula is [1] Q1 = ¼(n + 1)th Term. The formula gives you the place. For example, the 7th or 55th place. Example: Find the lower quartile for {27, 1, 2, 6, 4...
In data science find the spread of a data set can often lead to clues about the statistical relationship between the data points. The interquartile range is a useful type of spread since it is not affected much by outlying extremes. The interquartile range of a data set is the difference ...
How to calculate the inner quartile range. This is calculated by subtracting Q1 from Q3. This can be named IQR Next you will need to calcuate the upper and lower limit of your range or your data. You can do this by following the formula below: Lower range limit = Q1 – (1.5* IQR)....
Then you do have to put a lower bound, since this distribution returns 0% probability only when a point is infinitely far away from the mean value. But the good thing is that (if the assumptions are true) this bound will nicely adapt to each different dataset, because of its exponential...
Below is the formula to calculate the range for this data set: =MAX(B2:B11)-MIN(B2:B11) The above formula finds the maximum and the minimum value and gives us the difference. Quite straightforward… isn’t it? Also read:Calculate Interquartile Range (IQR) in Excel ...
third quartiles, calculate the interquartile range by subtracting the value of the first quartile from the value of the third quartile. To finishing the example used over the course of this article, you would subtract 8.5 from 17 to find that the interquartile range of the data set equals ...

Calculate your lower fence = Q1 – (1.5 * IQR) Use your fences to highlight any outliers, all values that fall outside your fences. Your outliers are any values greater than your upper fence or less than your lower fence. Example: Using the interquartile range to find outliers ...
Now, let’s find the lower quartile. The lower quartile is in the (25+1)2 = 12.5th place. So, it’s the average of the 12th and 13th number, which are both 6. Then, the lower quartile is 6.Finally, we do a similar process to find the upper quartile. The upper quartile is ...
