Biositatistics for Clinical Trials on Cancer
This course introduces methods and concepts of biostatistics and epidemiology that researchers who conduct clinical research (including nursing research, epidemiological research, etc.) should understand.
The course explains concepts required for both interventional and observational studies.
It is not simply a cookbook on how to use statistical software, but the goal is to enable audiences to plan their own research, interpret the results, and critically examine them.

Describing Data
Describing Data
When summarizing continuous data such as age or laboratory results, do you think that you should provide the median and range? Can you explain why it's not the average?This lecture will explain the basics, such as interpreting data using histograms and scatter plots, and choosing analysis methods.This lecture will also explain data cleaning and preliminary analysis that should be performed before conducting tests or estimations.

Hypothesis Testing 1
Hypothesis Testing 1
This lecture will explain the basics of statistical hypothesis testing.You might always see p-values in papers and academic presentations, but do you accurately understand the definition and concept of p-value?Take this lecture and become able to explain it yourself.

Hypothesis Testing 2
Hypothesis Testing 2
This lecture focuses on cases where the outcome is continuous or categorical variables.Don't you easily assume that "Wilcoxon's log rank test is used for datasets with small N and continuous variable" or "Fisher's exact test is used for those with small N and categorical variable"?This lecture will explain appropriate understandings of the testing.

Survival Analysis
Survival Analysis
This lecture will explain survival analysis, which is a particularly important analytical method in clinical cancer research.This method is required when the outcome is survival. Why is it inappropriate to use analytical methods for continuous or categorical variables? This lecture will provide you the basic concepts of survival analysis.
