First Statistic Class

This school year, it was my first class for introductory statistics which sound really complicated to me, as a student who has no idea about this college-level subject. A statistic is nothing connected to algebra, it’s another level of math which requires dot-connecting, analyzing, and comprehension skill to understand and extract the knowledge of new concepts from the statistic books. The correlation coefficient (R) is one of the hardest and exiting unit so far from the past two months of learning in this course. We learned to look at different scatterplots data and a linear regression line to understand how does the explanatory and response variables correlate with each other. Using the correlation formula to calculate the R-value is impossible and it kind of wasting our time. So calculator features come to be really handy to run the the two-variable stats, graph the scatter plot and calculate the linear regression line’s equation. Our group had sent out a survey to ask the students and facilitators for a data sample that we could use to find different the correlation between the two variables. I was involved in finding the correlation between the number of siblings versus the number of friends on Facebook. I really enjoyed learning about the statistic since it isn’t just about a number but it taught me to be a better person to be able to analyze data and make a good usage out from the skill.
