Question

does distance affect world record running time?
identifying components of cer
use the following information to answer the question about claim, evidence, and reasoning.

experiment:
the world record times for several olympic running events are compared.

data table:
distance (meters) | time to complete (seconds)
100 | 9.58
200 | 19.19
400 | 43.03
1600 | 223.13

which of the following would be a claim statement for a cer?

• the distance affects the world record time.
• the world record affects the distance.
• the distance does not affect the world record time.

Explanation:

Analyze the experimental question and variables

Independent variable: Distance (meters)
Dependent variable: Time to complete (seconds)
Question: Does Distance Affect World Record Running Time?

Evaluate the data table trends

As distance increases (\(100 \to 200 \to 400 \to 1600\)), the time to complete also increases (\(9.58 \to 19.19 \to 43.03 \to 223.13\)).

Determine the correct claim statement

The data shows a direct relationship where distance affects the world record time.

• Option 1: "The distance affects the world record time." (Correct)
• Option 2: "The world record affects the distance." (Incorrect direction of causality)
• Option 3: "The distance does NOT affect the world record time." (Contradicts the data)

Answer:

• (A) The distance affects the world record time. (Correct answer)
• (B) The world record affects the distance.
• (C) The distance does NOT affect the world record time.
