Question
Problem statement: It is common knowledge that there is a significant positive relationship between height and weight. However, Kuya raised the question on whether we become more wise as we get older. He collected data on both variables. Is there a relationship?
The appropriate test for this problem is:
t test for one sample
t test for dependent samples
t test for independent samples
one-way ANOVA
repeated measurements ANOVA
correlation analysis
linear regression
multiple regression
one-variable chi-square
two-variables chi-square
Problem statement: It may be a myth but many people believe that we can predict someone’s adult height based on height at age 2 (you double that height). Kuya gathered a sample of 30 toddlers and measured their height at their second birthdays. Then he went back and measured their height at their 25th birthdays. He wanted to see how tall his own son who was measured at 33 inches on his second birthday. What can be expected of his height when he turns 25?

multiple regression
one-variable chi-square
two-variables chi-square
Explanation / Answer
(a)
Correct option:
one variable chi- square
EXPLANATION: one way chi squaretest evaluated whether a categorical variable followsa hypothezed population distribution. Here,wise is a categorical variable.
(b)
Correct option: Linear regression
EXPLANATION:
Linear regression is applied for studying relationship between two quantitative variables. Here, the two quantitaive variables are heights at the age of 2 and 25.
