These milestones enable us to track specific events so we can identify certain conditions through the course of a project. In the case of our landscape project we have five milestones inserted into our Gantt chart. They are at task 2 Design backyard‚ task

T-test for Two Independent Samples * This test is used when only two unrelated groups are being compared and the measurements are either interval or ratio. The two groups may or may not have the same number of samples. * The t-test for two independent groups involves testing whether or not there is a significant difference between the population means of the two groups. Consider a study wherein the effectiveness of banana leaves as an organic wrapper was compared to that of aluminum foil

Analysis of Variance Lecture 11 April 26th‚ 2011 A. Introduction When you have more than two groups‚ a t-test (or the nonparametric equivalent) is no longer applicable. Instead‚ we use a technique called analysis of variance. This chapter covers analysis of variance designs with one or more independent variables‚ as well as more advanced topics such as interpreting significant interactions‚ and unbalanced designs. B. One-Way Analysis of Variance The method used today for comparisons of

statistics‚ a sample is a subset of a population. Typically‚ the population is very large‚ making a census or a complete enumeration of all the values in the population impractical or impossible. The sample represents a subset of manageable size. Samples are collected and statistics are calculated from the samples so that one can make inferences or extrapolations from the sample to the population. This process of collecting information from a sample is referred to as sampling. A complete sample is a set
