PSYCH 10 Study Guide - Final Guide: Sampling Error, Dont, Standard Deviation
Document Summary
If the null were true, the expected slope would be 0. Residual error: difference between sampling error and residual error, residual= within model error. Sampling error- (cid:271)etwee(cid:374) (cid:373)odel error . your predi(cid:272)tio(cid:374) of the populatio(cid:374) will (cid:272)ha(cid:374)ge. Why is it more close to sampling bias than sampling error?: researcher has bias going into the study (trying to find something about it) Reasons for any slope to occur: chance, real slope representative of population (there is an effect) T is just a ratio (slope/variation in the slope due to chance if the null were true) If t = 5 then the slope is 5 times larger than. If the null were true, the expected sample estimate of the relationship of the variable would be 0 (no relationship). However, this is only a sample of the population that isn"t representative of the entire population.
