How do you find the upper and lower fence in Excel?
[Lower Fence = Quartile 1 – (1.5 * IQR)]. Calculate the Upper Fence by adding 1.5 times the Interquartile Range to Quartile 3. [Upper Fence = Quartile 3 + (1.5 * IQR)].

Calculation of quartile deviation can be done as follows,
- Q1 is an average of 2nd, which is11 and adds the difference between 3rd & 4th and 0.5, which is (12-11)*0.5 = 11.50.
- Q3 is the 7th term and product of 0.5, and the difference between the 8th and 7th term, which is (18-16)*0.5, and the result is 16 + 1 = 17.
How do you find the lower quartile from raw data?
Lower Quartile and the Method of Finding it for Raw Data
- If n is not divisible by 4 then the mth variate is the lower quartile, where m is the integer just greater then n4.
- If n is divisible by 4 then the lower quartile is the mean of the n4th variate and the variate just greater than it.
- So, n4 = 114 = 2.75.
