Question

Use R Code:

An experiment was conducted to determine the effect of germination time (in days) and temperature (degrees C) on the free alpha amino nitrogen (FAN) content of rice malt. The values shown in the following are the treatment means of FAN with n = 2 (data from Anche and Okafor 1989) Temperature 24 Days 28 Row Means 50.98 72.40 86.72 26 39.4 49.9 55.159.5 56.4 68.0 76.488.8 70.2 81.5 95.6 99.6 Column Means 55.33 66.47 75.70 82.63 Grand Mean 70.03 The total sum of squares was 8097. Draw an interaction plot for these data Compute an ANOVA table and determine which terms are needed to describe the means

Explanation / Answer

R Code

read the CSV to r using the following code

var1 <- read.csv("germinate.csv")

temp <- c(rep('22',3),rep('23',3),rep('26',3),rep('28',3))

weight <- c('var1$x22','var1$x24','var1$x26','var1$x28')

weight

df <- data.frame(temp,weight)

View(df)

plot(weight ~ temp, data = df)

var1.aov <- aov(weight ~ temp, data = df)

summary(var1.aov)

use interaction.plot to get the interactions
