Interpreting Results with Practical Examples
Example 1: With a data set where Q1 is 10 and Q3 is 20, the IQR would be 10. The upper fence is calculated as Q3 + (1.5 * IQR) giving us 35 as the upper limit for outliers.
Example 2: If Q1 is 15 and Q3 is 50, the IQR is 35. Multiplying this by 1.5 gives us 52.5. Subtracting this from Q1, the lower fence is -37.5, and adding it to Q3, the upper fence is 102.5.

How do I calculate the upper and lower fences? Multiply your dataset's interquartile range with 1.5, then add and subtract that from your dataset's first and third quartiles, respectively. Those are your upper and lower fences.
Calculate the Lower Fence by subtracting 1.5 times the Interquartile Range from Quartile 1. [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)].
The lower fence is equal to the 1st quartile – IQR*1.5.The upper fence is equal to the 3rd quartile + IQR*1.5. As you can see, cells E7 and E8 calculate the final upper and lower fences. Any value greater than the upper fence or less than the lower fence is considered an outlier.
They are calculated by finding the midpoint between the upper limit of one class and the lower limit of the next class. For example, if one class interval is 10-19 and the next is 20-29, the upper-class boundary of the first class is 19+ (20−19)/2 = 19.5 and the lower-class boundary of the next class is also 19.5.
The lower and upper bounds of the CI are always on the right side of the output under “L.Limit” and “U.Limit”. Rounding to one decimal place, we have 12.0 to 14.8.
To find the upper bound of your data range, multiply the interquartile range by 1.5 and add it to your third quartile value to create a formula such as "=C2+(1.5*C3)." To find the lower bound of your data range, multiply the interquartile range by 1.5 and subtract it to from your first quartile value to create a ...
The lower quartile is the mean of the values of the data point of rank 6 ÷ 2 = 3 and the data points of rank (6 ÷ 2) + 1 = 4. The result is (15 + 36) ÷ 2 = 25.5. The upper quartile is the mean of the values of data point of rank 6 + 3 = 9 and the data point of rank 6 + 4 = 10, which is (43 + 47) ÷ 2 = 45.
You can manually calculate quartiles with several formulas to verify your information: Lower quartile = (N+1) x 1/4. Middle quartile = (N+1) x 2/4. Upper quartile = (N+1) x 3/4.
The lower boundary of each class is calculated by subtracting half of the gap value 0.012=0.005 0.01 2 = 0.005 from the class lower limit. On the other hand, the upper boundary of each class is calculated by adding half of the gap value 0.012=0.005 0.01 2 = 0.005 to the class upper limit.
The formula for the upper control limit (UCL) is: UCL = target mean + (3 * standard deviation / sqrt(sample size)) The formula for the lower control limit (LCL) is: LCL = target mean - (3 * standard deviation / sqrt(sample size)) The factor of 3 in the formula is based on the assumption that the process follows a ...
The upper and lower bounds of a rounded number are the biggest and smallest values that the number could have been before it was rounded. We often round numbers to a given degree of accuracy, for example to the nearest 10 10 or to 1 decimal place.
