Lean Six Sigma
Project: | Healthcare | |
Deliverable: | Expected Variation | How do I determine if it's approximately normal? |
Mean: | ROUND ALL FINAL RESULTS TO 3 DECIMAL PLACES. | |
Standard deviation::: | ||
Is the data approximately bell shaped? | Yes or No | |
What is the lowest point of expected variation? | ||
What is the upper point of expected variation? |
1. Calculate the average for each. |
2. Calculate the standard deviation for each. |
3. From these calculations, determine the range of expected variation. |
4. Create a histogram from this data. Use the |
appropriate number of cells to represent the data. |
Hint: There is a 'rules of thumb' cell choice table in the HISTOGRAM (part I) section of your workbook. 5. By looking at the histogram, is the process approximately normally distributed? Is there obvious assignable-cause variation?
here is the data:
