level of measurement, scientific reports, and statisitcal testing Flashcards
key sections of scientific report
- abstract - summary
- introduction - background research leading to hypothesis
- method- detailed procedure
- results - findings
- discussions - explanation
- referencing - full list of sources
how are books and journal articles referenced
books - author, date, title, place of publication , publisher
journals - authors, date, article title, journal name, volume , pages
when can the sign test be used
test for a difference ( not correlation)
used a repeated measures design ( related data)
uses nominal data
how do u conduct a sign test
- State hypotheses (alternative & null).
- Record data & assign a sign (+ or -).
- Find S (number of times less frequent sign appears).
- Compare S to critical value (use p≤0.05).
- State conclusion (accept/reject null hypothesis).
what 3 factors determine which inferential test to use
experimental design (related/unrelated)
level of data( nominal/ordinal/interval)
types of study ( difference /correlation)
whats the rule of R
✔ If the test name contains R → calculated value must be gReater than or equal to the critical value.
✔ If no R → calculated value must be less than or equal to the critical value.
