Research question: do people who own pets vs. not differ in their phobia of spiders? and non-pet owners on their phobia scores. Degrees of freedom would be n-2 45 t crit is. 2021 using fourty to be conservative. Test variable is dv and grouping variable would be pet ownership. Analyze compare means independent samples t test. I. test variable (dv) = spider phobia score. Ii. grouping variable (iv) = pet ownership those values yes and no respectively.
