Define an experiment-wise error rate.

Short Answer

Expert verified

The risk of making a type I error applies to comparing the treatment means in the experiment. Thus, the value 伪selected is called an experiment-wise error rate.

Step by step solution

01

Concept of the error rate

A percentage error is a frequency with which a specific probabilistic testing procedure results in type I or II error.

02

Defining the experiment-wise error rate

The risk of making a type I error applies to comparing the treatment means in the experiment. Thus the value 伪 selected is called an experiment-wise error rate.

P(Type I error) = 伪

The experiment's error rate is also called the familywise error rate.

In general, we take 伪=5%

What are the treatments for a designed experiment that uses one qualitative factor with four levels鈥擜, B, C, and D?

Robots trained to behave like ants. Robotic researchers investigated whether robots could be trained to behave like ants in an ant colony (Nature, August 2000). Robots were trained and randomly assigned to 鈥渃olonies鈥� (i.e., groups) consisting of 3, 6, 9, or 12 robots. The robots were assigned the task of foraging for 鈥渇ood鈥� and to recruit another robot when they identified a resource-rich area. One goal of the experiment was to compare the mean energy expended (per robot) of the four different colony sizes.

a. What type of experimental design was employed?

Study of mutual fund performance. Mutual funds are classified as large-cap funds, medium-cap funds, or small-cap funds, depending on the capitalization of the companies in the fund. Hawaii Pacific University researchers investigated whether the average performance of a mutual fund is related to capitalization size (American Business Review, January 2002). Independent random samples of 30 mutual funds were selected from each of the three fund groups, and the 90-day rate of return was determined for each fund. The data for the 90 funds were subjected to an analysis of variance, with the results shown in the ANOVA summary table below.

a. State the null and alternative hypotheses for the ANOVA.

Explain the difference between an experiment that employs a completely randomized design and one that employs a randomized block design.

What is the difference between a one-way ANOVA and atwo-way ANOVA?
