Psychological Statistics: ANOVA with interaction: Did the colour of the light (Green or Amber) influence speed, i.e. was there a main effect of Colour. Did presence or absence of a Red Light camera alter speed, i.e. was there a main effect of Camera. Did the effects of light Colour and presence of Camera interact.

Please see attached for full question. 5 Road accident researchers were interested in the effectiveness of Red Light cameras that can photograph the number plates of cars if they pass through an intersection on a red light. Researchers arranged for speeds to be measured as cars entered intersections. There were two factors under consideration - Presence or Absence of a red light camera, and whether cars were facing a Green or Amber light. The data was collected at four times of day. (a) Did the colour of the light (Green or Amber) influence speed, i.e. was there a main effect of Colour. On a standard answer sheet, state clearly the null and alternative hypotheses (in words) ... click for more

Which SPSS analysis to use - paired sample t-tests etc.?

I'm only at the very beginning of learning psychology and I'm struggling with which analysis to use for which type of experiment. For example if I answer questions like below: 1. type of study, experimental or correlational? - experimental 2. type of data from DV, categorical or continuous? - continuous 3. How many conditions? - 2 4. type of design, within-participants or between-participants? - within The answers above would indicate that I should use a Paired Samples T Test. But what if I changed the answer to question 4 to between participants? I'm just a little confused over which inferential statistic to use for which types of experiements.

correlational analysis, analyses of differences between two conditions, measure of association in statistics

correlational analysis, analyses of differences between two conditions, measure of association in statistics - definitions and examples please.

This job shows when to use ANOVA or T-test.

I've done a study for my course. It involved showing participants a picture with a context statement above it. There are two conditions; 1=picture with a negative statement 2=picture with a neutral statement. Participants are then asked to select what they think the boys in the picture are about to do. There is a list of options, some are negative and some are neutral. So I have the following options to analysis - I think..... - Negative statement & negative selection made - Negative statement & neutral selection made - Neutral statement & negative selection made - Neutral statement & neutral selection made I'm sure this is quite simple if I had more exposure to the differe... click for more

Memory, Thinking, and Intelligence

Research Spearman's Model if Intelligence and Gardner's Multiple Intelligences. Based on your findings, compare and contrast the two models. Provide several comparisons and several contrasts. And two models do you feel is more in line with psychology today? appropriate external sources. and which you are frferring to someone else's writing, cite any sources used and format them according to the requirements of apa style guide.
