Matthew is great at making the complex seem simple! Patient and thorough and willing to follow-up when additional help is needed.

I picked up on the first assumption of OLS, another way to interpret the null hypothesis testing and the actual interpretation of confidence intervals.

After getting D's and C's on his algebra I tests and quizzes, my 9th grade son got an A on a quiz after only his second session with David. My son describes David as calm, patient and able to describe concepts in a way that he (my son) can understand easily. Awesome start!
