Step 5:Find the Interquartile Range IQR value. To find the Deduct Q1 value from Q3. IQR = Q3-Q1 Step 6:Find the Inner Extreme value. An end that falls outside the lower side which can also be called as a minor outlier. Multiply the IQR value by 1.5 and deduct this value from Q1...
Now to calculate the IQR, we simply subtract the quartiles: $$Q_3 - Q_1 = 18-3 = 15 $$ So, the IQR is 15! Here is a boxplot for this data showing the median and quartiles: Boxplot of this example Here is another example: 3 3 7 8 10 11 15 15 20 27 Once again, to ...
Calculate 1.5 * IQR: 1.5 * IQR = 1.5 * 13 = 19.5 Subtract from Q1 to get your lower fence: 5 – 19.5 = -14.5 Add to Q3 to get your upper fence: 18 + 19.5 = 37.5. Add your fences to your data to identify outliers: (-14.5) 1,2,5,6,7,9,12,15,18,19,(37.5),38. Anyth...
We refined a formula to calculate the volume of this fluid using the Zeiss IOLMaster 700, based on specific eye measurements. We found that the volume measurements from both devices were very similar, showing a strong agreement. The study also discovered that eyes with pseudoexfoliation...
IQR = Upper Quartile−Lower QuartileIQR = 25.5 – 20.5IQR = 5Answer: IQR = 5Example 2: What will be the upper quartile for the following set of numbers? 26, 19, 5, 7, 6, 9, 16, 12, 18, 2, 1.Solution:The formula for the upper quartile formula is Q3 = ¾(n + 1)th ...
Said differently, low outliers shall lie below Q1-1.5 IQR, and high outliers shall lie Q3+1.5IQR. One needs tocalculate median, quartiles, including IQR, Q1, and Q3. The outlier formula is represented as follows, The Formula for Q1 = ¼ (n + 1)thtermThe Formula for Q3 = ¾ (n...
If we calculate the mean (average) income on this block, the NBA player's salary will skew the results of our study. Certain measures, including the mean, standard deviation, and variance, are particularly sensitive to outliers, and so it is very important to know that an outlier is ...
Step 4:Now, we calculate the interquartile range (IQR). IQR = Q3-Q1 = 19-8 = 11 Since the IQR is 11, it tells us that the middle 50% of values in the dataset fall within a range of 8 to 19. This means that the values within this range are not very diverse or spread out....
