Question

A developmental psychologist conducted an experiment to examine the effect of type of text used on math performance across age groups. Fifth grade and college students studied age-appropriate math concepts using either a traditional hard copy book text or an e-text available on the web. Performance on a math test of the concepts studied was then measured for all students.
The appropriate statistical test to analyze the data in this study is ______.

Answer 1

Answer:

an ANOVA

Explanation:

ANOVA known as Analysis of Variance is used to carry out analysis in the differences among group means in a sample. ANOVA is all about the collection of statistical models and their associated estimation.

The model is based on the law of total variance. Simply, ANOVA is used to provide a statistical test of whether there are two or more population means which are equal and it then generalizes the t-test beyond means. Ronald Fisher, an evolutionary biologist and statistician developed ANOVA.

Answer 2

Answer:

An ANOVA

Explanation:

ANOVA which is referred to as Analysis of Variance was developed by Statistician and Evolutionary Biologist called Ronald Fisher. It is a statistical method helpful in testing three or more variables.

It is a method used to determine the difference between two or more means or components through significance tests. It also shows ways to make multiple comparisons of several subjects topics.

The Anova test will be most ideal in analyzing the performance data of students who used traditional hard cover textbooks and the e- textbooks on the web.
