TOWES - Test of Workplace Essential Skills Data Interpretation and Graphs Questions and Answers — Questions and Answers
Question 1: Refer to the bar chart titled 'Daily Production Output by Shift.' A supervisor needs to identify the shift that produced the fewest units. Which shift should be identified? **Daily Production Output by Shift** (A bar chart shows the following values: Shift A = 120 units, Shift B = 150 units, Shift C = 110 units)
- Shift B
- Shift A
- Shift C (Correct answer)
- All shifts produced the same number of units
Correct answer: Shift C
The bar representing Shift C is the shortest on the chart, corresponding to the lowest value on the vertical axis, which is 110 units. Shift A produced 120 units and Shift B produced 150 units.
Question 2: According to the line graph 'Weekly Storage Temperature,' what was the general temperature trend in the storage unit from Tuesday to Thursday? **Weekly Storage Temperature** (A line graph shows the following data points: Monday = 4°C, Tuesday = 6°C, Wednesday = 8°C, Thursday = 5°C, Friday = 7°C)
- It decreased then increased
- It steadily increased
- It remained constant
- It increased then decreased (Correct answer)
Correct answer: It increased then decreased
To determine the trend, follow the line from Tuesday to Thursday. The data point for Tuesday is at 6°C, it rises to 8°C on Wednesday, and then falls to 5°C on Thursday. Therefore, the temperature increased and then decreased.
Question 3: The pie chart 'Quarterly Workplace Incident Causes' breaks down the reasons for incidents. Which of the following is the single largest cause of incidents for the quarter? **Quarterly Workplace Incident Causes** (A pie chart shows the following percentages: Slips & Falls = 45%, Improper Lifting = 30%, Equipment Malfunction = 15%, Other = 10%)
- Slips & Falls (Correct answer)
- Improper Lifting
- Equipment Malfunction
- Other
Correct answer: Slips & Falls
The 'Slips & Falls' section of the pie chart is the largest slice, representing 45% of the total incidents, which is a higher percentage than any other category.
Question 4: Using the 'Monthly Rainfall Data' bar chart, calculate the difference in rainfall between the month with the most rain and the month with the least rain. **Monthly Rainfall Data** (A bar chart displays the following rainfall amounts: May = 80 mm, June = 120 mm, July = 150 mm, August = 90 mm)
- 30 mm
- 70 mm (Correct answer)
- 120 mm
- 150 mm
Correct answer: 70 mm
First, identify the highest and lowest values from the chart. The highest rainfall was in July (150 mm) and the lowest was in May (80 mm). The difference is calculated as 150 mm - 80 mm = 70 mm.
Question 5: A quality control inspector is reviewing the 'Hydraulic System Pressure Test' line graph. What was the approximate pressure (in PSI) recorded at the 2-minute mark of the test? **Hydraulic System Pressure Test** (A line graph shows pressure over time. Key data points are: 0 min = 0 PSI, 1 min = 500 PSI, 2 min = 1200 PSI, 3 min = 1500 PSI, 4 min = 1400 PSI)
- 500 PSI
- 1500 PSI
- 1400 PSI
- 1200 PSI (Correct answer)
Correct answer: 1200 PSI
To find the pressure at the 2-minute mark, locate '2' on the horizontal (time) axis. Move vertically up to the data point on the line, and then horizontally across to the vertical (pressure) axis to read the corresponding value, which is 1200 PSI.
Question 6: A manager is using the 'Daily Defect Report' bar chart to monitor quality. According to company policy, any production line with more than 10 defects requires immediate review. Based on the chart, which line must be reviewed? **Daily Defect Report** (A bar chart shows defects per line: Line 1 = 8, Line 2 = 12, Line 3 = 5)
- Line 3
- Line 1
- Line 2 (Correct answer)
- No lines require review
Correct answer: Line 2
The chart shows that Line 1 has 8 defects, Line 2 has 12 defects, and Line 3 has 5 defects. The policy requires a review for lines with *more than* 10 defects. Only Line 2, with 12 defects, exceeds this threshold.
