One Sample t Test in R | Understand P Values in t Test | Hypothesis Testing in R
This video is about Student’s t test for one sample in R. This test is used when you have observations only on one variable. To perform t test, first we set null hypothesis and alternative hypothesis. We also check any outliers in the data using a boxplot before running the analysis. Two examples are provided in this video. The explanation of p value and interpretation of results of t.test function are also discussed in this video.
t.test function is used to calculate t test in R. The output of t.test function gives t statistic, degrees of freedom, p value, alternative hypothesis, confidenance interval, mean of data. On the basis of p value, you can accept or reject null hypothesis.
