İstatistiksel bir yöntem seç

Bir öğrencinin en sevdiği spor (basketbol, beyzbol, futbol) ile büyüdüğü yer (kentsel, kırsal) arasında istatistiksel olarak anlamlı bir ilişki olup olmadığını bilmek istiyoruz. Bunu test etmek için rastgele seçilmiş 100 öğrenciye büyüdükleri yerin türünü ve en sevdikleri sporu sorabiliriz.

Bir öğrencinin en sevdiği spor ile büyüdüğü yer arasında istatistiksel olarak anlamlı bir ilişki olup olmadığını en iyi biçimde belirlemek için hangi testi kullanırsın?

What is survey data, and how do we determine which statistical test to use to analyze the data? To answer this, you’ll be able to define all sorts of survey data types, encounter important concepts like descriptive and inferential statistics, and visualize survey data to determine the appropriate statistical modeling technique needed. In doing so, you will know how to best qualitatively and quantitatively define the trends and insights you come across in surveys.

In this chapter, you’ll learn the different ways of creating sample survey data out of population survey data by analyzing the parameters by which the survey data was taken.

Exercise 1: Random sampling Exercise 2: Random sample of employees Exercise 3: Reproducible random sampling Exercise 4: Stratified Random Sampling Exercise 5: Spread of yes's and no's Exercise 6: Stratified sampling Exercise 7: Weighted sampling Exercise 8: Blog survey Exercise 9: Weighted sampling on handedness Exercise 10: Cluster Sampling Exercise 11: Group clusters Exercise 12: Choosing clusters Exercise 13: Cluster sampling analysis

Now it’s time to understand the difference between descriptive and inferential statistics concerning survey data analysis with some real-life examples. Through hands-on exercises, you’ll further interpret the meaning of different variables, key measures such as central tendency and zscore, and interpret results for actionable steps.

Last but not least, it’s time to apply statistical modeling to survey data analysis with regression analysis, the two-sample t-test, chi-square test, and interpret the assumptions associated with these tests.
