Statistic

The statistic is a very new and complex topic that we start to study this school year. Our unit 3 topic mainly about scatterplot, response and explanatory variables, linearity, correlation, associations, and their summaries, R and R-Squared, residuals, least square regression lines, outliers and influential points on a scatterplot, transformations (minor topic), reading computer outputs and how to use functions in the calculator. When we studied scatterplot I have a hard time of how to interpret the slope because if we missed said of any important words everything is going to mess up. My math teacher, Jeff, say my name in class to identify the slope then interpret the slope. I was so shocked and nervous because I have no idea what to explain, and every word I have in my head kind of mess up. The words that I always keep in mind: explanatory, response, predicted, changing Y over changing X. When I started to interpret the slope, it wasn’t correct. But does it stopped me? I know for sure I need to work two times harder than my fellow classmate of how to be confident of how to interpret the slope. Outside of class time after lunch, I came to ask my teacher to explain deeper and another way that I can understand it better. It took him only 15 minutes to explain. I took all the note and try to remember clearly of how to interpret the slope. From that time on whenever there is a question to interpret the slope, Jeff would call out my name and complete the question. Before our Christmas break, we took the test and finally I interpret slope correctly.
