chance. According to Dr. Mirabella (2011)‚ if the observations are not equivalent to the expectations‚ then that is the time to observe and track more directly and gather more information. Chi-Square testing is one of the simplest techniques to use and the most applicable (Mirabella 2011). Therefore‚ we use hypothesis testing to see if we should dig further for more additional information. Even more‚ we utilize this test to show a comparison of observed and expected values.

At about 100 d.f.‚ the distribution becomes symmetrical. The area under each chi-square distribution is equal to 1 or 100%

MB 0050 Research Methodology Ques 1 Research is a sequential method of enquiry‚ directed towards a clear implicit or explicit objective. Describe in detail the steps to be carried out in a typical research study. Ans. Different scholars have interpreted the term ‘research’ in many ways.

My Journey into Tai Chi For the past month and a half‚ once a week I go to my Tai Chi session. I took Tai Chi is a way for me to lightly exercise during my first year in college. In the beginning I found Tai Chi to be a little difficult and at times I was unsure what exactly I was supposed to do. Prior to my weekly sessions‚ I had no knowledge of martial arts. I’ve never even heard of Tai Chi. Attending all my Tai Chi classes‚ reading Master C.K Chu’s book Why Tai Chi? Questions & Answers‚ and my

2.3. The Chi-Square Distribution One of the most important special cases of the gamma distribution is the chi-square distribution because the sum of the squares of independent normal random variables with mean zero and standard deviation one has a chi-square distribution. This section collects some basic properties of chi-square random variables‚ all of which are well known; see Hogg and Tanis [6]. A random variable X has a chi-square distribution with n degrees of freedom if it is a gamma

1. What is the meaning of research? There are various definitions of research. According to John .W. Best‚ research is a systematic and objective analysis and recording of controlled observations that may lead to the development of generalizations‚ principles‚ theories and concepts‚ resulting in prediction for seeing and possibly ultimate control of events. On the other hand‚ Clifford Woody defined research as a careful enquiry or examination in seeking facts or principles‚ a diligent investigation
