PS2024

and then she says to me "kill me now kill me now kill me now"

TermDefinition
systematic source of variability/systematic variance variance due to the manipulations we have introduced in the study (in other words those that are under our control, our effects)
unsystematic source of variability/unsystematic variance error variance; due to chance factors which are typically out of our control and which have not been varied systematically across participants in the study.
t-test statistical test for comparing two different means
ANOVA/analysis of variance statistical test allowing comparison of more than two different means
within group variation = experimental error; assumed the same between all groups individual differences/experimenter error/chance factors
between group variation why means differ across groups condition effects + experimental error
F ratio between group variation / within group variation = 1 if no condition effects > 1 if condition effects
type 1 error rejecting the null hypothesis where it should have been accepted defined by α-level
α-level the probability level on which the decision to accept the null hypothesis is based (usually p > 0.05)
effect size family of indices giving us information about the strength of effect(s) allows: assessment of treatment magnitude (IV on DV) comparison of effects with other studies aggregation of results for meta analysis estimation of required sample size
eta-squared (η²) η² = SSeffect/SStotal proportion of total DV variance attributed to an effect closer to 1 = larger effect
partial eta-squared (partial η²) ηp² = SSeffect/(SSeffect + SSerror) less biased than η² (takes less of design into account)
ω2 measure of effect size estimate of how much variance in the DV is accounted for by the IVs less biased alternative to eta-squared, especially when sample sizes are small. ω2 = (SSeffect – (dfeffect)(MSerror)) / (MSerror + SStotal)
ωp2 ωp2 = (SSeffect – (dfeffect)(MSs/Cells)) / (SSeffect + (N - dfeffect)MSs/Cells)

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
