Z-score The data should be symmetrical. Lower fence Q1 15IQR Upper fence Q3 15IQR where IQR stands for interquartile range which represents the difference between the 75th percentile Q3 and 25th percentile Q1 in a dataset. How to Find Interquartile Range.

This calculator uses this formula to automatically calculate the upper and lower outlier boundaries for a given dataset. This means that the outer fences are 50 - 30 20 and. Calculate What is lower and upper fence.

Where IQR is Interquartile Range. An observation that lies above the upper fence or below the lower fence is often considered to be an outlier. 6 For the diastolic blood pressures the lower limit is 64 -.

We often declare an observation to be an outlier in a dataset if it has a value 15 times greater than the IQR or 15 times less than the IQR. IRQ Q3 - Q1. Press the Calculate button to see the results.

The median splits the data set into lower and upper halves and is the value of the second quartile Q 2. It will give you the calculated IQR first quartile second quartile and third quartile. Outliers are values below Q 1-15Q 3-Q 1 or above Q 3 15Q 3-Q 1 or equivalently values below Q 1-15 IQR or above Q 3 15 IQR.

This means that the inner fences are at 50 15 35 and 60 15 75. Upper and Lower Fence Calculator. The interquartile range IQR is the range in values from the first quartile Q 1 to the third quartile Q 3.
