... Note: The two sample t test assumed that the two samples were independent of each other. There are many occasions where the two samples are not independent because they involve the same sampling unit. Example: Marketing Pre-Test of a New Ball-Point Pen ...

Descriptive statistics
... We select the level of confidence we want (usually 95% in biological work - see the notes below) and multiply by the tabulated value. If was 138.8 9.65 m, then the 95% confidence interval would be 138.8 9.65x1.96 m, or 138.8 18.91 m. In other words, if we were to repeat this experiment over a ...
