Introduction to Biostatistics Some Basic Concepts
... When n = 11, then the median is the 6th observation. * If n is even, there are two middle observations. The median will be the mean of these two middle observations. It will be the (n+1)/2 th ordered observation. When n = 12, then the median is the 6.5th observation, which is an observation halfway ...

For the following hypothesis test where H0: ≤ 10 vs. Ha: > 10, we reject H0 at level of significance and conclude that the true mean is greater than 10 when the true mean is r ...

Lesson 1: Summarizing and Interpreting Data
... Our daily lives often involve a great deal of data, or numbers in context. It is important to understand how data is found, what it means, and how the information is used. The focus of this lesson is on how to calculate and understand statistics—the numbers that summarize, describe, or represent set ...

... To edit a table or object (an object is a group of results) you first need to double click on the table/object so an “editing” box appears around the table/object, and then select the value you want to modify. An “editing box'” will be a ragged box outlining the table. If you only do a single clic ...
