Document Summary
The cause must come before the effect! Ma- complied of estimates of other people"s studies. Putting bits and pieces together to create an experiment. The significance of the outcome is dependant on the sample size. The biggestest correlation is between the first born and verbal iq. Meaning the first born will be ever so slightly better at. Overall, the relationships were so low, it"s somewhat safe to say that birth order and ocean traits don"t have a relation. There are always problems with science, even when done well. After doing constant experiments, you may resort to the null most times. A small effect will be significant in a large enough sample. Take the correlation (. 08 in the iq vs birth order) You have an 80% chance of determining iq in a family of. Motivation to write up interesting, significant research; others get forgotten in a file drawer .
