Solution:
Let us consider the following variables: Score in Tests, Hours of Study and Financial Condition of the Student's Family...
Here, we just want to find a linear relationship among these variables... In this regard, we can collect a sample of students (say from 10 respondents) and then ask them about the number of hours that they study per day. Analyse their financial condition and then rate it on a predetermined scale (say 1 to 5)...
Later on we can determine the linear relationship among these variables...
Process/Instrument: Multiple Regression in Excel/R/Minitab/ SPSS etc...
Sample Solution:
So, the linear equation is:
Score = 3.72 + 1.92*Hours + 0.125*Economic Condition...
Excel Solution:
The Excel output is:
The Regression Equation
is:
Score = 3.72 + 1.92*Hours + 0.125*Economic Condition...

SELECT ALL THAT APPLY. Regression a. examines relationship
between ordinal variables. b. is a linear prediction model. c. is
bivariate if it involves one independent and one dependent
variable. d. is multiple if it involves two or more independent and
one dependent variable. 16. SELECT ALL THAT APPLY. In the linear
regression equation Y = a + b (X) a. X = the score of the
independent variable b. a = the Y-intercept c. b = the slope of the...

relationship between two variables. (a) Distance (b) size (c)
strength (d) direction 2. 10 pairs of sample data were obtained
from a study which looked at household income and the number of
people in the household who smoked (cigarettes). The value of the
linear correlation coefficient r was computed and a result of -
