a research design that uses a separate sample for each treatment condition/each population is called an ________-____________ research design, or a ___________-___________ design.
- independent-measures
- between-subjects
Independent-measures t statistic formula differs from single-sample test (Ch9) in that

the independent-measures t is basically a two-sample t that doubles all the elements of the single-sample t formulas.

i-m t = sample mean difference - pop mean difference / estimated standard error

(M1-M2) - (m1 - m2) / s(M1-M2)
Independent-measures t statistic uses a new formula for estimated standard error, which is

s(M1-M2) = square root of (s²₁/ n₁) + (s²₂ / n₂)
basic information containted in t

t= data - hypothesis / error
