STAT 380 6/9/2025
This class gave a great introduction to statistics and some of the
terminology needed to build a basic understanding. We started the lesson by
learning what data is and terms like variables and observational units. It then
transitioned into statistical inference and how we use samples to better
understand the population. I really enjoyed the in-class exercises because they
were relatable with many of them being about UNL. We moved onto descriptive
statistics and how we use that information in multiple different ways. There was a
good refresher on topics like median and mean that we probably learned in middle
school or even earlier. The measures of variability section was also a good
refresher on variance and standard deviation. I learned about these topics a few
years ago and while I have used them a couple times, it’s always good to relearn
them or catch up on them. As these are standard statistical tools, I am glad we
covered these for future use in this lecture. I think exercise 7 and 8 were good
because they showed multiple ways to use the formulas from standard deviation
and variance. The slides from part 2 were also helpful with relearning some plots
and charts that I haven’t used before and how to visualize them. I have never used
a dot plot in any of my studies, but I understand them now and am ready to use

The slides from part 2 were also helpful with relearning some plots and charts that I haven’t used before and how to visualize them. I have never used a dot plot in any of my studies, but I understand them now and am ready to use

them in this class. The histogram and scatter plot will also be useful in data collection and interpretation. Overall, this first lecture was a good refresher on many statistic formulas and ideas and sets a good foundation for the rest of this class.
