- Q1
For items 1-5, refer to this study;
Romina farms conducted a research on the type of feed which will produce more efficient and more productive chickens. Twenty five chicken (hens) were used as subject in this study. Four groups where fed using the different feed formulas. One group of chicken where not given any of the feed treatment. Five feed formulas were compared. Data on the following factors were recorded: number or eggs produce per day, egg size, egg color intensity.
What is the independent variable in the study?
growth of chicken
number of eggs
time of feeding
type of feed formula
30s - Q2
What is the dependent variable?
time of feeding
amount of feeds
number of eggs produced per day
number of chicken
30s - Q3
What is the experimental unit used in the study?
number, size and egg quality
five feed formula
chickens
egg color intensity
30s - Q4
Which of the following is/are constant variable/s in the study?
none of the above
egg color
age of chicken
growth of chicken
30s - Q5
What is the purpose of one group of chicken which are not subjected to the five feed formulas?
dependent group
independent group
experimental group
control group
30s - Q6
Feed formulas, number of egg, size and egg color intensity are factors being investigated in the study. What do you call to these factors?
Trials
Treatment

inferring
formulating hypothesis
measuring
predicting
30s - Q9
Why are dependent variables known as the Responding Variables?
because they are held constant
because they are controlled in the experiment
because they are the observed effects or behavior.
because they manipulated by the investigator
