Abstract Eight students participated in a study of the Irrelevant Speech Effect. Irrelevant speech disrupts immediate serial recall. In this study we test the disruptive effects of irrelevant speech on serial recall. In this experiment participants saw a list of randomly ordered digits 1-9. During the some trials they heard irrelevant speech in the background‚ while other trials were quiet. This irrelevant speech was a passage from Franz Kafka in German (Francis‚ Neath‚ & VanHorn‚ 2008)

Bivariate analysis Contingency table In this case‚ we use contingency table to analyze the relationship between 2 qualitative variables. And this test works by comparing expected and observed frequencies with x2 distribution. Correlation coefficient When we need to test the relationship between 2 quantitative variables‚ we use correlation coefficient and it measured by standardized covariance measure and investigates linear dependence. Before doing this‚ it is better to first make a scatterplot

CHAPTER I Introduction The Philippines is an agricultural country. Almost 75% of our total population are farmers especially in the rural areas. Therefore‚ the country is producing different kinds of crops for home consumption and for the farmers as source of livelihood. But today‚ we are suffering from food shortage because of our growing population. This study aimed to help our local farmers in terms of knowledge on how to produce sufficient crops

Calculate the mean square for 1) gender‚ 2) marital status‚ 3) interaction between gender and marital status‚ and 4) error or within variance. Calculate the F ratio for 1) gender‚ 2) marital status‚ and 3) interaction between gender and marital status. Identify the critical Fs at alpha = .05 for 1) gender‚ 2) marital

Chapter 2. Randomized Complete Block Design 2.1 Randomized Complete Block Design 2.1.1 Examples When examining the effect of a factor‚ it is often helpful to remove the effect of excess variation through the use of blocking. A blocking variable is one that may affect the variation of the response‚ but is unrelated to the primary hypothesis of interest. The desired result is to have homogeneous experimental units within each block so that when the blocking effect is removed (through modeling)

What are the degrees of freedom for 1) gender‚ 2) marital status‚ 3) interaction between gender and marital status‚ and 4) error or within variance? 1. A-1= There are 2 groups of gender; male and female‚ so it would be 2-1=1 as the degree of freedom. 2. B-1= There are 3 groups for marital status; married‚ single‚ and divorced‚ so it would be 3-1=2 as the degree of freedom
