What is Stability Factor in six sigma?
Stability factor is defined as the proportion of Q1 to Q3 (Quartile 1/ Quartile 3) and is a measure of the dispersion of the population. A SF of 1 is the most desirable. SF < 0.9 indicates control issues and SF > 0.9 indicates technology issues.

How do you do interquartile range step by step?
Step 1: Find the upper quartile, Q3.Step 2: Find the lower quartile: Q1.Step 3: Calculate IQR = Q3 - Q1.Step 1: Find the upper quartile, Q3.Step 2: Find the lower quartile: Q1.Step 3: Calculate IQR = Q3 - Q1.Step 1: Find the upper quartile, Q3.Step 2: Find the lower quartile: Q1.Step 3: Calculate IQR = Q3 - Q1.Step 1: Find the upper quartile, Q3.Step 2: Find the lower quartile: Q1.Step 3: Calculate IQR = Q3 - Q1.
How do you find the IQR of a number set?
To find the interquartile range (IQR) of a number set, first, arrange the data in ascending order. Next, identify the first quartile (Q1), which is the median of the lower half of the data, and the third quartile (Q3), the median of the upper half. Finally, subtract Q1 from Q3 (IQR = Q3 - Q1) to determine the range of the middle 50% of the data.
What is the equation of interquartile deviation?
Interquartile deviation Qd=(q3-q1) / 2
Procedure for calculating quartile deviation for raw data?
procedure: step 1: arrange your raw data in increasing order. step 2: find the Q1 is the size of the (n+1)/4th value. step 3: find the Q3 is the size of the 3(n+1)/4th value. Quartile Deviation(QD)= (Q3-Q1)/2 for example: 87 ,64,74,13,19,27,60,51,53,29,47 is the given data step 1: 13,19,27,29,47,51,53,60,64,74,87 step 2: (n+1)/4=3 therefore Q1=27 step 3: 3(n+1)/4=9 therefore Q3=6 implies QD=18.5
What is quartiles?
The quartile deviation(QD) is half the difference between the highest and lower quartile in a distribution.
What is the outlier in 64 67 68 69 73 75 79?
There is no agreed definition of outliers. However two common criteria to identify outliers are: Method I: If Q1 is the lower quartile and Q3 the upper quartile then any number smaller than Q1 - 1.5*(Q3 - Q1) or larger than Q3 + 1.5*(Q3 - Q1) is an outlier. By that criterion there is no outlier. Method II: Assume the numbers are normally distributed. then outliers are with absolute z-scores greater than 1.96. Again, there are no outliers.
How do you calculate first and third quartile?
first quartile (Q1) : Total number of term(N)/4 = Nth term third quartile (Q3): 3 x (N)/4th term
