A scatter plot shows data points mostly following an upward trend from left to right. What type of correlation does this represent?
Answer: Positive correlation
Points trending upward from left to right show a positive correlation between the two variables.
Scientists measure rainfall (mm) and river depth (m) over 6 months. As rainfall increases, river depth also increases. This relationship is best described as:
Answer: Directly proportional
When one variable increases as the other increases proportionally, the relationship is directly proportional.
A data table shows that an ice cube's mass decreases over time as it melts. After 10 minutes it has lost 40% of its mass. If it started at 50 grams, what is its current mass?
Answer: 30 g
40% of 50 g = 20 g lost, so 50 − 20 = 30 g remaining.
A graph shows two lines: one for indoor temperature and one for outdoor temperature over 24 hours. The indoor line changes much less than the outdoor line. What does this tell us?
Answer: Indoor conditions are more stable than outdoors
A line with smaller variation indicates more stable conditions, showing indoors is better regulated.
A scientist conducts an experiment with a control group and an experimental group. What is the purpose of the control group?
Answer: To provide a baseline for comparison
The control group provides a baseline with no treatment applied, allowing comparison with the experimental results.
A frequency table shows how many students scored in each grade range on a science test. The 70–79 range has the highest frequency. What does this mean?
Answer: Most students scored between 70 and 79
Highest frequency in the 70–79 range means more students scored there than in any other range.
An experiment measures how quickly sugar dissolves in water at different temperatures. Results show it dissolves fastest at 80°C. Which conclusion is best supported?
Answer: Higher temperature increases the rate of dissolving
Since dissolving rate increases with temperature and peaks at 80°C, higher temperature speeds up dissolving.
