Question

1. what is a key factor in determining the reliability of data?

a. the color scheme used in graphs
b. the number of data points collected
c. the type of data representation used
d. the credibility and bias of the source

Explanation:

• Option a: Color scheme in graphs is for visual appeal, not data reliability.
• Option b: Number of data points affects sample size but not the reliability of the source itself.
• Option c: Data representation type (e.g., chart type) is about presentation, not reliability.
• Option d: Credibility (trustworthiness) and bias (unfair favoritism) of the source directly impact data reliability. A non - credible or biased source may provide inaccurate or skewed data.

d. The credibility and bias of the source
