Third, instrumental variable (IV) approach explores the determinants of these dimensions. Using a 59-item SEPQ and 506 student responses at a leading Australian university, the study identified four dimensions (
Histograms serve as an excellent starting point for more detailed and complex statistical analyses. By providing a rapid, comprehensive view of a dataset's distribution, they help analysts decide whether additional tests, such as ANOVA, Chi-square, t-test, or regression analysis, should be run. ...
Ridge Regression is a methodology to handle the scenarios of the high collinearity of the predictor variables. This helps to avoid the inconsistancy.

Internet usage is the percentage population with an internet connection. Results are estimated using a cross-sectional logit regression model with heteroscedasticity-robust standard errors. p-values are given in parentheses. ***, **, and * represent statistical significance at the 1%, 5%, and 10%...
