ordinal
A if you finish first, B if second - what kind of measurement?
ratio
categories go in order AND distances are the same AND zero means zero (height)
interval
categories go in order AND distances are the same BUT zero doesn't mean zero (ex. Celsius scale of temp. 1 degree to 2 degree and 21 degrees to 22 degrees is the same, but 0 degrees is NOT the absence of heat, so it is not zero) (ex. How most self-report measurements go)
ordinal
categories that go in order (1 is better than 2 is better than 3). Difference between 1 and 2 is NOT the same as 2 and 3) (Running a race, times)
test-retest
consistent scores every time we test 1. Relevant when measuring constructs (ex. Intelligence)
interrater
consistent scores no matter who is rating (look at PP slide 17) 1. Relevant when measuring observational measures
respect for persons, beneficence, justice
three principles of the bellmont report
test-retest, interrater, internal
three types of reliability
predictive and concurrent
two types of criterion-related validity?
physiological
type of scale: - biological (brain waves, pulse, blood pressure, skin conductions)
Self-report
type of scale: ask questions and answer them (usually range from strongly agree to strongly disagree; or "How do you feel about class"?
observational
type of scale:- Watch something happen and record data
face and content
what two types of validity are subjective?
pearon product moment correlation
index of linear relationship between two continuously measured variables
discussion
"one of the major limitations of the study is nutrition" goes in what part of the article?
internal
- also called "coefficient alpha" - consistent scores no matter how you ask 1. Split half reliability - correlation between halves of the same test 2. Cronbach's alpha - an average of all of the possible item-total (split-half) correlations
nominal
- categories can't be ordered. (men and women, no order)
variance
Average squared deviation of scores from the mean
boxplot
Graphic representation of the five number summary (first and third quartile define the ends of the box)
phi coefficient
Index of correlation between two variables measured along a dichotomous nominal scale
spearman rank-order correlation
Index of correlation between two variables measured along an ordinal scale
point-biserial correlation
Index of correlation between two variables, one of which is measured on a dichotomous nominal scale and the other on at least an interval scale.
self-report, observational, physiological
Three types of scales psychologist use
e
When quoting, a. provide the author's name in the text b. provide the year and the page citation in the text c. include the complete reference in the reference list d. do only a and c e. do all a, b, and c
pearson product-moment correlation (r)
Which correlation is the correlation between two continuous variables?
.1, .3, .5
___ low, ___ moderate, ___ strong
0.7
number you need for good reliability for internal consistency
standard deviation
square root of the variance
