Question

Oscar did a research project about the use of sunscreen and the number of freckles a person has. Before he did the project, he predicted that the more sunscreen a person used, the fewer freckles he would have. The scatter plot below shows the result of his research.Did the research support his prediction? O No, because his prediction was a negative correlation and the results show no correlation. Yes, because his prediction was a positive correlation and the results show a positive correlation. Yes, because his prediction was a negative correlation and the results show a negative correlation. O No, because his prediction was a positive correlation and the results show no correlation.

Answer 1

The statement of Oscar that the more sunscreen a person used, the fewer freckles he would have, is a negative correlation.

Now, given the scatter plot, we can see that the points don't have neither positive or negative correlation. Therefore, the research DID NOT support his prediction of a negative correlation, since the results show no correlation.
