Karten in diesem Stapel (38)
- 1what does the strength of the significant difference depend on?the size and difference between the means
power increases as means become further apart - 2what does the amount of variation of scores within the conditions mean?Power decreases as scores within conditions become more different
- 3what is a factorial design?any experimental design with more than one factor
- 4in factorial design what are IVs called?factors
- 5in factorial design what are conditions called?levels of a factor
- 6how many types of 2-way factor design are there?3
- 7what is Independent Groups (IG) factor design use?different participants in all conditions of IV
- 8what is Repeated measures (RM) Factorial Designuses the same particpants in all conditions of both IV
- 9What is mixed factorial designSame participants complete all conditions of one IV
but different participants used in all conditions of the second IV. - 10what is Sphericityassumption that variances of difference scores is equal
- 11when is sphericity used?applies to Within-subjects factors
- 12when is sphericity calculated for IVs?when there are two or more conditions
- 13in sphericity what happens when the test is not significant (above 0.05)assume Sphericity as the assumption has not been broken
- 14what happens if the test is significant (below 0.05)se the Greenhouse-Geisser adjusted F and p values from the Tests of Within Subjects Effects table.
- 15What are the steps for running an independent t-test1. insert data into SPSS
2. go to analyse compare means
3. select independent sample t-test
4. move the depend variable into test variable box - 16What are the steps for running an independent t-test CONTINUED5. move the independent variable into the grouping variable box
6. Click define groups
7. Code the groups
8. Run the test - 17what are the steps for running a dependent t-test1. insert data into SPSS
2. go to analyse
3. go to compare means
4. select paired sample t-test - 18what are the steps for running a dependent t-test CONTINUED5. put both variables in to the paired variables box
6. hit okay - 19how do you write up data from a t-test if it was in lab report style?In paragraph form, describe the data, report the mean & SD and than the results from the t-test
- 20How do you write results from a t-test?t(df) = t, p= significance
- 21how do you make a graph with one-way anova1. select graphs
2. go to legacy dialog
3. select the line graph
4. open the line charts dialog box
5. select simple - 22how do you make a graph with one-way anova CONTINUED6. select summarise and than hit define
7. put the IV in the cat axis box
8. click options to add error bars
9. select standard deviation
10. set the multiplier to 1
11. hit ok - 23what chart do you look at if levenes significance is gr8r than 0.05 in ANOVAwhen the levene significance is higher you ONLY look at the ANOVA chart
- 24do you want the LEVENE significance to be gr8r than 0.05yes because it shows that its not significant
- 25How do you interpret independent groups ANOVA if the data on levenes is gr8r 0.05(F(df1,df2) = F value from anova, p= ANOVA sig
- 26what are the steps for conducting independent groups ANOVA1. variable view to define the variables
2. define the variables in measure
3. assign categories, go to value
4. insert the value & label and add them
5. enter the data using the value given in the right column - 27what are the steps for conducting independent groups ANOVA Continued6. select analyse
7. go to compare means
8. select one way ANOVA
9. move the dependent variable into the dependent list
10. move the IV in the factor box - 28what are the steps for conducting independent groups ANOVA Continued11. select options
12. select descriptives
13. selct homegeneity of variance & welch
14. hit okay - 29what are the steps for conducting independent groups ANOVA Continued15. check to make sure levenes sig if gr8 than 0.05 if so use ANOVA table
- 30what table do you use if the sig value is less than 0.05?the Robust tests of equality of means
- 31What are the steps for pairwise comparisons for independent groups ANOVA1. return to the one-way anova dialog box
2. select post hoc
3. select the test you wish to use
4. click continue than ok - 32what is a t-test a test of? a) difference b) relationship c) associationA) Difference
- 33why is a t-test known as students t rather than the name of the developer?because the developer worked for Guiness & published his work on the side
- 34How many variables can be involved in a single -test at any one time?2
- 35what does a levenes test tell us?if the assumption of homogeneity was broken making the test significant or if it wasn't broken making the test insignificant
- 36if a question asks what were the results of a levenes test. where do you look?at the Levene part of the table
- 37if the t-test is significant, what t-value and significant value would you report?the equal of variances not assumed row
- 38what does ANOVA stand for?Analysis of Variance
