Use the given file for this assignment. You are interested in predicting a father’s education level (dependent variable) when you know the mother’s education level (independent variable). The variable names are "paeduc" and "maeduc." Determine the linear regression equation for predicting the father’s education level from the mother’s education. Answer the following questions: How much of the total variance have you accounted for with the equation? Based upon your equation, what level of education would you predict for the father when the mother has 16 years of education?

The objective of this analysis is to explore the relationship between a mother’s education level and a father’s education level using linear regression. The variables under investigation are "maeduc" (mother’s education) and "paeduc" (father’s education). The goal is to develop a predictive model that estimates the father’s education based on the mother’s education and to interpret the model’s effectiveness and practical implications.

To begin, a scatterplot was generated to visually assess the relationship between the two educational variables. The scatterplot displayed a positive association, indicating that higher maternal education is generally associated with higher paternal education. A line of best fit was added to the scatterplot, serving as the linear regression model’s estimated relationship between the variables. The line of best fit minimizes the sum of squared differences between observed values and the predicted values from the model, providing the most accurate linear approximation of the data.

The linear regression equation derived from SPSS output takes the form: paeduc = b0 + b1 maeduc, where b0 is the intercept and b1 is the slope coefficient. Based on the analysis, the regression equation was calculated as: paeduc = 4.32 + 0.45 maeduc. This indicates that for each additional year of maternal education, the father’s education level increases on average by 0.45 years. The intercept value suggests that if the mother had zero years of education, the predicted father’s education would be approximately 4.32 years, which may not be meaningful in practical terms but is necessary for the regression model.

Of particular interest is the R-squared value, which indicates the proportion of variance in the father’s education explained by the mother’s education. In this case, the R-squared was approximately 0.22, meaning about 22% of the variability in fathers’ education levels can be accounted for by mothers’ education. This suggests a moderate but limited predictive power and indicates that other factors also influence paternal education levels beyond maternal education.

Using the regression equation, the predicted level of a father’s education when the mother has 16 years of education can be calculated as: paeduc = 4.32 + 0.45 * 16 = 4.32 + 7.2 = 11.52. This prediction suggests that when a mother has 16 years of education, the father’s education level is estimated to be approximately 11.52 years, which corresponds roughly to some post-secondary education or partial college completion.

In addition to numerical analysis, a scatterplot with the line of best fit provides a visual confirmation of the relationship. The plot illustrated a clear upward trend, supporting the linear regression model’s appropriateness. The line of best fit visually summarizes the overall direction and strength of the relationship, emphasizing how increases in mother’s education correlate with increases in father’s education.

Overall, this analysis indicates a positive association between the educational levels of mothers and fathers. The regression model explains a modest portion of the variance, highlighting the influence of other unmeasured factors impacting paternal education. This type of analysis can be valuable for understanding family educational dynamics and for predicting educational attainment within family studies.
