Solving an anova problem
What probability level did you choose and why? What would be the null hypothesis in this study? Thus, the Tukey Test was developed to answer such questions. The company is trying to predict the current salary of its employees from their starting salary both expressed in thousands of dollars. The data referred to in this question were collected on 41 employees of a large company.
I need the f statistic and probability. Notice that the formula labeled the “Tukey Criterion”, Eq. Answer Neuroscience researchers examined the impact of environment on rat development. What would be the alternate hypothesis?
Impoverished wire mesh cage – housed alone , standard cage with other rats , enriched cage with other rats and toys , super enriched cage with rats and toys changes on a periodic basis. The Tukey Test is an extension of ANOVA. Thus, in the execution of a set of Tukey Tests for 6 pairs of means, the formula for the Tukey Criterion will be your single critical value while you would have 6 calculated values, one for each pair of means. The data for the maze task is below. Compute the appropriate test for the data provided below.
Rats were randomly assigned to be raised in one of the four following test conditions: The calculated values are actually the sample mean differences for each pair of means under consideration. The drawback to the ANOVA is that when you have rejected the null hypothsis and determined that at least one pair of means are not equal, this information is rarely sufficient to base managerial decisions on.
After two months, the rats were tested on a variety of learning measures including the number of trials to learn a maze to a three perfect trial criteria , and several neurological measure overall cortical weight, degree of dendritic branching, etc.
