Does stress effect heart rate in individuals?

Null T-test Hypothesis:

Stress does not have an effect on heart rate levels.

Independent Variable (DV) = category of stress

a.) relationships

b.) work

c.) money

Dependent Variable (DV) = heart rate (manipulation of stress changes rate levels) (Giraud, 2014).

One-Way ANOVA, one IV w/multiple categories and one DV (Giraud, 2014).

Null One-Way ANOVA Hypothesis:

Different types of stress have the same or no effect on heart rate levels.

IV = different types of stress:

1. relationships

2. work

3. money

DV = heart rate resulting from the stress (Giraud, 2014)

Two-Way ANOVA, two IV w/multiple categories and one DV (Giraud, 2014).

Null Two-Way Hypothesis:

Stress in men and/or women have the same or no effect on heart rate levels.

IV = different types of stress separated by gender:

Male

a.) relationships

b.) work

c.) money

Female

a.) relationships

b.) work
