Question.1860 - This week marks the end of our learning journey! We have learned about descriptive and inferential statistics and - hopefully - challenged ourselves to think about how statistics can help us in our current/future careers. As we begin to prepare for Exam 3 and the cumulative final, I thought it would be great to use this discussion board as a space to ask questions, answer questions, share similar frustrations, etc.! For the initial post, please share 2-3 concepts/tests you learned about. You can ask questions, share definitions of specific concepts and/or tests, and offer helpful tips for your colleagues to better understand material from chapters 1-10. Have a jingle to help you remember key concepts? Share it! Have a creative way of organizing the content (e.g., poster, flash cards)? Let us know!
Answer Below:
I enjoyed learning statistics throughout the semester. Right from the basics of statistics, what and why statistics should be used till chapter 10 correlation and regression, I enjoyed dealing with data, analyzing and interpreting them. Two of the most exciting concepts were in Chapter 2, the graphical representation of data, and Chapter 3, Measures of central tendency and dispersion. In Chapter 2, I learned about organizing and summarizing data. Frequency distribution helps count the number of data sets provided to find the percentages and proportions. I also learned about new terminologies: cumulative frequency distribution, which means the sum of frequencies and all the values below them, and cumulative percentage distribution, which means the percentage of frequencies and all the values below them. Chapter 2 also discusses the graphical distribution. Some include pie charts, line graphs, histograms, bar graphs, and time series charts. These graphs represent the visuals of data. With respect to Chapter 3, I learned about the three measures of central tendency and five measures of dispersion. Mean is the average of the data, Median is the middle number of data, and Mode is the frequency of a number in the data. Range, variance, standard deviation, Index of quality variation, and interquartile range are all measures of dispersion. Overall, It was a great learning.More Articles From Statistics
