Lower and Higher Fence Calculator for Wood

To calculate the lower and higher fences for the Wood data, we would need to apply the Interquartile Range (IQR) method. Here’s how the fences are calculated:

1. Calculate Quartiles (Q1 and Q3):

• Q1: The first quartile is the median of the lower half of the data (25th percentile).
• Q3: The third quartile is the median of the upper half of the data (75th percentile).

2. Find the Interquartile Range (IQR):

• IQR = Q3 – Q1

3. Calculate the Lower and Higher Fence:

• Lower Fence = Q1 – 1.5 * IQR
• Higher Fence = Q3 + 1.5 * IQR
