Ramsay Test Data Interpretation & Analysis 3 — Questions and Answers
Question 1: A line graph shows production peaking at noon and dropping by evening. What can you conclude about evening output?
- It is lower than at noon (Correct answer)
- It is higher than at noon
- It is the same as noon
- It cannot be determined
Correct answer: It is lower than at noon
A drop after the noon peak means evening output is lower.
Question 2: A reading must stay between 90 and 110 units. A gauge shows 115. What is the correct interpretation?
- The reading is above the acceptable range (Correct answer)
- The reading is within range
- The reading is below range
- The reading is exactly at the limit
Correct answer: The reading is above the acceptable range
115 exceeds the upper limit of 110, so it is out of range high.
Question 3: A histogram shows most measurements clustered near 50 mm with few outliers at 70 mm. What does this suggest?
- Most parts measure close to 50 mm (Correct answer)
- Most parts measure 70 mm
- All parts are identical
- The data is evenly spread
Correct answer: Most parts measure close to 50 mm
Clustering near 50 mm means that value is most common.
Question 4: A worker compares two pumps: Pump 1 uses 5 kWh/hr, Pump 2 uses 3 kWh/hr. Over 8 hours, how much more energy does Pump 1 use?
- 16 kWh (Correct answer)
- 24 kWh
- 40 kWh
- 8 kWh
Correct answer: 16 kWh
The 2 kWh/hr difference over 8 hours equals 16 kWh.
Question 5: A control chart point falls outside the upper control limit. What action is typically indicated?
- Investigate the process for a problem (Correct answer)
- Ignore it as normal variation
- Lower the control limit
- Stop recording data
Correct answer: Investigate the process for a problem
A point beyond control limits signals a special cause that should be investigated.
Question 6: A table shows scrap rates: Line 1 at 3%, Line 2 at 7%, Line 3 at 5%. Which line is most efficient in reducing scrap?
- Line 1 (Correct answer)
- Line 2
- Line 3
- All equal
Correct answer: Line 1
Line 1's 3% is the lowest scrap rate, making it most efficient.
Question 7: A meter reading increases from 1,250 to 1,400. What is the total increase?
- 150 (Correct answer)
- 250
- 100
- 350
Correct answer: 150
1,400 minus 1,250 equals 150.
A line graph shows production peaking at noon and dropping by evening.
What can you conclude about evening output?
