A colleague of yours is completing a final report on the causes of the frequency of cyberbullying. In this report, she is asked to identify the causes that most strongly impacted the frequency of cyberbullying. She conducts an OLS regression. What statistic do you advise her to use in her discussion? Why?
Homework Answers
Statistic recommended: 
, 
and F-statistic
Reason: to see the level of
fit. Represents the
amount of variation explained in target variables by regressors.
This helps in deciding if the data is able to explain the variation
in response variable or not!
: this helps in deciding whether a particular variable is
significant in explaining the response variable. So if we want to
check if a particular variable has significant effect on the
frequency of cyber bullying or not then this statistic is
useful.
F-statistic is basically ratio of Mean sum of square due to regression and Mean square due to error. It explains the total validity of model much like R-squared.

She tests 45 bilingual people and counts the number of words from this list they define correctly. Data Bilinguals Monolinguals Observed 30 15 From a...
