Question 1: The frequency distribution is an organized tabulation of the collected data that has these two corresponding columns.

 
a. A data values column, when data is ungrouped, or a classes column, when data is grouped, and a frequency column
b. A data values column, when data is grouped, and a tally column
c. A classes column, when data is ungrouped, and a frequency column
d. A classes column, a tally column and a frequency column
 
Question 2: Which of the following is a graph that does not only present a visualization of the organized tabulation of the collected data for a study?
 
a. Histogram
b. Frequency polygon
c. Scatter plot
d. Regression line
 
Question 3: This is the equation of the regression line for two collected data, Height and Weight, of a study on the Biomechanics of Athletes, with the values x for Weight and values y for Height, that estimates and predicts values of y, Height, from values of x, Weight, based on the quantities of the two data of the study.
 
Regression line: y=mx+b
 
a. Regression line: Weight=m(Height)+b
b. Regression line: Weight=b(Height)+m
c. Regression line: Height=m(Weight)+b
