E-learning 5This is the first time I have attended a class in this format and wondered how effective it would be. It was very effective and therefore I would definitely introduce all my friends and family to attend classes in the same format. The instructor was very knowledgeable and provided a wealth of information about the current version, especially since the last version I used was several releases ago.

Information Technology 5I have twenty plus years of experience taking training courses. I am not easily impressed, reserved with my praise, and do not usually complete surveys. My instructor is excellent, the best I've experienced on a software subject, and I couldn't imagine him doing a better job of seamlessly walking students through a breadth of information in a remote environment. He did a fabulous job packing everything and addressing student questions. I am very impressed.
E-learning 5We just wanted to let you know that the service provided, from registration to training is a very positive experience for everyone. We intend on taking more classes in the future and referring any new hires as well as friends/family members to take courses at World Class Education

Lesson 9: THE DETERMINATION OF THE APPROPRIATE SIZE OF A SAMPLE OBJECTIVES
Sample size determination is the act of choosing the number of observations or replicates to include in a statistical sample. The sample size is an important feature of any empirical study in which the goal is to make inferences about a population from a sample. In practice, the sample size used in a study is determined based on the expense of data collection, and the need to have sufficient statistical power. In complicated studies there may be several different sample sizes involved in the study: for example, in a survey sampling involving stratified sampling there would be different sample sizes for each population. In a census, data are collected on the entire population, hence the sample size is equal to the population size. In experimental design, where a study may be divided into different treatment groups, there may be different sample sizes for each group.
