WebTo get Q1 you need 25% of the data to the left and 75% to the right. Step 2: Multiply the number of values you have – there are 10 values here – times the quartile you want (Q1 = .25) .25 * 10 = 2.5. Then, look at the result. In this case the result is 2.5 (a decimal value). WebWe can use the IQR method of identifying outliers to set up a “fence” outside of Q1 and Q3. Any values that fall outside of this fence are considered outliers. To build this fence we take 1.5 times the IQR and then subtract this value from Q1 and add this value to Q3.
WebJan 29, 2024 · In statistics, the upper and lower fences represent the cut-off values for upper and lower outliers in a dataset. They are calculated as: Upper fence = Q3 + (1.5*IQR) Lower fence = Q1 – (1.5*IQR) where IQR stands for “interquartile range” and represents the difference between the 75th percentile and 25th percentile in a dataset.
