If we have three or more population means to compare‚ why can’t we test

Q1.Explain the process of problem identification with an example. Answer : Problem Identification – A Process : One of the most important first tasks of research is to identify and define clearly the problem you wish to study. If you are uncertain about the research problem or if you are not clear in your own mind about what you want to study‚ others who read your proposal will also be uncertain. A well-defined research problem statement leads naturally to the statement of research objectives

ANOVA Test Paper This week Team C is looking to further our knowledge of hypothesis tests by testing for variances and simultaneously comparing the different means of gasoline to conclude if the populations sampled were equal or not. We will test whether the three sample are from populations with equal variances. This type of testing is called analysis of variance or ANOVA (Lind‚ Marchal‚ & Wathen‚ 2004). The ANOVA test can be conducted with the intent of giving families information on where the

Analysis of Variance (ANOVA) One Way Classification Random samples of size n are selected from each of k populations. It will be assumed that the k populations are independent and normally distributed with means [pic][pic] and common variance [pic]. We wish to derive appropriate methods for testing the hypothesis: [pic] [pic] [pic] at least two of the means are not equal. Table 1 K random samples | |Population
