A researcher is interested to determine if there is a relationship between playing violent video games and aggressive behavior. The researcher asks students to keep track of how much time they spend playing violent video games over a two-month period. The researcher also collects ratings from teachers on the aggressiveness of each student (higher rating means more aggressive). The researcher finds a correlation of r = +.70 between these two variables. Describe what this + .70 relationship means in terms of type direction and magnitude What percent of the variance in playing violent video games is shared with aggressiveness (that is, what is the coefficient of determination) Also explain what it means. A newspaper sees this study in a journal and writes an article about the findings. The headline of the newspaper article is \"Study finds playing violent video games causes kids to be violent.\" Is this headline accurate Why or why not Write a headline that you think is appropriate. Match the type of correlation with the correct scatterplot. Positive Correlation Negative Correlation No Correlation

Solution

1.1.Describe what this +0.70 relationship means interms of type,direction,magnitude

sol : positively correlated

1.3 sol:

This article is right as r=0.70 is a significant correlation and cannot be 0 at any time
