Suppose we conduct an experiment in which we vary the brightness contrast on a computer monitor and measure how many words a person can read from that screen in 1 minute. Use the following results to answer the questions:

Low Brightness & Contrast High Brightness & Contrast

Mean = 150 words Mean = 175 words

Standard Deviation = 50 words Standard Deviation = 10 words

Question 1: Which brightness contrast condition produced the most consistent results? Why do you say that?

Question 2: Of the two conditions, which one do you think will contain the single participant who read the most words in one minute? Why?
