When specifying the formula for a new variable, you have to option to include or not include spaces around the equals sign and/or after the commas between arguments in a function. D we find that with df= 14 the critical value of t at .05 level is 2.14 and at .01 level is 2.98. The term multivariate analysis refers to the analysis of more than one variable.
