The question asks about the direction of bias in the estimated coefficient on hours devoted to study (per course) when the number of campus social organizations is omitted from the regression explaining student GPAs at HUTB.
Option 1: positive. If the omitted variable (number of campus social organizations) is positively correlated with hours spent studying ......Login to view full explanation登录即可查看完整答案

Consider the following general model specification: 𝑌 = 𝑓 ( 𝑋 1 , 𝑋 2 , 𝑋 3 𝑋 4 , 𝑋 5 , 𝑋 6 , 𝑋 7 , 𝑋 8 ) . Where the 9 variables are: Y = Test score of the mid-term exam X1 = Time spent studying for the exam X2 = Degree of course difficulty (measured by an index #) X3 = Class size (number of students) X4 = Experience/knowledge of the teacher X5 = Student’s college experience (college credits previously earned) X6 = Quantity of the student’s outside (non-academic) activities X7 = Level of the student’s determination to succeed (measured by an index #) X8 = Dummy (=1 if the course is face-to-face; 0 otherwise (online)) For each of the 2 cases of omitted variables below, determine the sign (positive/negative) of the bias – you must complete columns 3, 4, and 5 in the table below. Case OM IN 𝛽 𝑂 𝑀 𝛼 1 − ℎ 𝑎 𝑡 BIAS 1 X5 X6 Sign is [ Select ] negative positive Sign is [ Select ] negative positive Bias is [ Select ] negative positive 2 X4 X1 Sign is [ Select ] negative positive Sign is [ Select ] negative positive Bias is [ Select ] negative positive
The bias caused by leaving a variable out of an equation is called
When we regress y on x1, we obtain the following simple regression line: 𝑦 ~ = 𝛽 ~ 0 + 𝛽 ~ 1 𝑥 1 (1). When we regress y on x1 and x2, we obtain the following multiple regression line: 𝑦 ^ = 𝛽 ^ 0 + 𝛽 ^ 1 𝑥 1 + 𝛽 ^ 2 𝑥 2 (2). The relationship between 𝛽 ~ 1 and 𝛽 ^ 1 is: 𝛽 ~ 1 = 𝛽 ^ 1 + 𝛽 ^ 2 𝛿 1 ~ (3), where 𝛿 1 ~ is the slope coefficient of the regression of x2 on x1, 𝑥 ~ 2 = 𝛿 ~ 0 + 𝛿 ~ 1 𝑥 1 (4). Let y = ln(wage), x1 = educ, and x2 = exper, where wage is hourly wage (measured in dollars), educ is years of formal education, and exper is years of labor market experience. Assuming 𝛽 ^ 1 , 𝛽 ^ 2 > 0, which of the following statements is correct?
