GED Science Data Interpretation Quiz

1. A scatter plot shows student study hours (x-axis) versus test scores (y-axis) with points showing a positive linear trend. What does this relationship indicate?

More study hours cause lower scores

Study hours and test scores are unrelated

More study hours correlate with higher scores

Test scores determine study hours

Submit

4. A heat map shows gene expression levels with colors ranging from blue (low) to red (high). Most cells show blue coloring. What does this indicate?

Gene expression is high overall

Gene expression is predominantly low

Expression is uniformly moderate

Data collection failed

5. A researcher compares two treatment groups using error bars showing 95% confidence intervals that do not overlap. What does this suggest?

The difference is likely not statistically significant

The difference is likely statistically significant

Sample sizes were too small

No conclusion can be drawn

6. A box plot displays test score distribution with median 75, Q1 70, Q3 85. What percentage of scores fall between Q1 and Q3?

25%

50%

75%

100%

7. A table shows mutation frequency in a population across generations: Gen 1: 0.01%, Gen 2: 0.02%, Gen 3: 0.04%. What trend is evident?

Mutations are decreasing

Mutation rate is doubling each generation

Mutations remain constant

Data is too small to assess

8. A dose-response curve shows drug effectiveness (%) rising steeply from 0–50 mg, then leveling off above 50 mg. What does this pattern indicate?

Higher doses are always more effective

Effectiveness plateaus at higher doses

The drug is ineffective

Dose has no effect on response

9. In a climate study, monthly precipitation data shows high variability (50–200 mm) with no clear seasonal pattern. What is the most accurate description?

Predictable seasonal rainfall

Highly variable and irregular precipitation

Consistent monthly totals

Declining precipitation trend

10. A table compares blood glucose levels (mg/dL) in fasting and fed states: Fasting 95, Fed 140. What does this difference indicate?

Glucose increases after food intake

The body maintains constant glucose levels

Fasting raises glucose

Glucose has no metabolic role

11. A scientist measures temperature changes over 10 hours and records: 20°C, 22°C, 25°C, 28°C, 30°C, 29°C, 27°C, 24°C, 22°C, 20°C. What trend does this data show?

Steady increase throughout the period

Temperature rose then fell in a roughly symmetrical pattern

Random fluctuations with no clear pattern

Continuous decrease after the midpoint

12. A line graph shows bacterial colony count (×10⁶) over 8 days: exponential growth from day 1 to day 5, then plateau. What does the plateau suggest?

Bacteria stopped reproducing

Nutrients or space became limited

Temperature decreased significantly

The measurement stopped working

13. In a toxicity study, the LD50 (lethal dose for 50% of subjects) is 500 mg/kg. What does this value represent?

The dose that causes no harm

The dose lethal to half the test population

The maximum safe dose

The minimum detectable dose

14. A pie chart shows nutrient distribution: Carbohydrates 45%, Protein 25%, Fat 20%, Other 10%. Which nutrient is most abundant?

Protein

Fat

Carbohydrates

Other

15. A researcher records heart rate (beats/min) before, during, and after exercise: 70, 140, 75. What does the post-exercise value indicate?

Heart rate remained elevated

Heart rate returned near baseline

Exercise had no cardiovascular effect

The measurement was inaccurate

16. A bar graph displays carbon dioxide levels (ppm) from 1960 to 2020. The bars show steady increases every decade. What inference can you make?

CO₂ levels have remained constant

CO₂ levels show an upward trend over time

CO₂ was highest in 1960

The data is unreliable

17. In a clinical trial, 80% of participants in the treatment group improved versus 20% in the control group. What does this suggest about the treatment's effectiveness?

The treatment has no effect

The treatment may be effective, but more trials are needed

The control group was poorly chosen

Environmental factors caused all improvements

18. A graph shows enzyme activity (%) versus pH. Maximum activity occurs at pH 7. Which pH level likely shows minimal enzyme function?

PH 4

PH 7

PH 10

Both a and c

19. A table shows plant heights (cm) at different light intensities (lux). As light intensity increases from 100 to 500 lux, height increases from 5 cm to 20 cm. What relationship is suggested?

Inverse relationship

Positive correlation

No relationship

Exponential decay
