An Inquiry into Relationships between Demographic Factors And Teaching, Social, and Cognitive Presence Hispanic 10,316 Asian 11 2,063 Age status Non-traditional Traditional 89,755 13,411 For the Teaching Presence subscale, the aggregate mean was 4.367 with a standard deviation of 0.806. Forward method linear regression resulted in three of the variables being statistically significant predictors of the criterion variable (the aggregate mean of teaching presence indicators) (Table 2).

The Forward method in SPSS enters predictor variables one by one in order of decreasing significance. Table 3, therefore, illustrates the changes in Adjusted R2, for the significant predictors of the criterion variable, as each variable is entered:
