Question

"Parents who constantly check mobile phones will raise children with short attention spans."

1. To adequately test this hypothesis, a researcher would conduct a(n)

2.The independent variable in this hypothesis is

3.The dependent variable in this hypothesis is

4. If designing an experiment with an experimental and control group, the control group is the group who......... checking mobile phones

Correlations

5.If you conducted correlational research and found a correlation of r = -.72 between amount of parental phone checking and children's attention span, what would you conclude (use the correlation coefficient to describe the relationship between these two variables; use parental phone checking and children's attention span in your response)?

6.If you conducted a correlational design, could you say that parental phone checking causes a change in children's attention span? Why or why not?

Answer 1

1) Regression analysis.

2) Independent variable is the time in hours spent on cell phones by parents

3) Dependent variable is Children's attention span.

4) Control group is do not check his smart phones during parenting time.

5) correlation is -0.72 which is negative and slightly close to -1. It means the variables independent and dependent are negatively correlated which means more time spent on cell phones by parents will lead to children with short attention's span.

6) Yes because as from the above example we can see that correlation is negative which means as the number of duration of cell phone is increases the children's attention span get decreased.
