Karten in diesem Stapel (15)
- 1Inferential statistics- techniques that allow us to study and then make generalizations about the population
- used to test hypothesis - 2sampling error- differences among groups which means sample is not 100% representative of population
- The extend to which the sample deviate from those that would be obtained from the entire population - 3hypothesis testing procedure1. state the hypothesis
2. state probability level
3. consult the statistical table
4. conduct the statistical test
5. accept or reject null hypothesis - 4state the hypothesisHo, Ha, H1, H2
- 5state the probability level- the probability that if an effect is found, it is due to sampling error
- 6consult the statistical table- computer program creates a p value
- rejects the null hypothesis if the p value is less than the alpha level - 7accept or reject null hypothesis- if the statistical test is significant then the Ho is rejected
- If it is non significant then the Ho is accepted and any difference is due to sampling error - 8statistical tests- 1 group t test
- 2 independent group t test
- 2 dependent group t test
- analysis of Variance (ANOVA)
- One way ANOVA
- Repeated measures ANOVA
- 2 way ANOVA - 91 Group t test- is the sample similar or different from a defined known population
- usually 2 alternate hypothesis so to a level it is set at two tailed - 102 independent group t test- are the 2 samples different from each other
- 112 dependent groups t testare 2 measures of the same sample different from each other
- 12Analysis of Variance (ANOVA)are more than 2 samples (different groups) different from each other?
- analyze whether or not the means if several groups are equal, and therefore generalizes the t test to more than 2 groups - 13One way ANOVA- with 2 groups will be the same as 2 independent group t test
- use ANOVA when there is more than 2 groups - 14Repeated measures ANOVA- analysis when a participant is measured on two or more occasions
- if there are only 2 measures for each participant: 2 dependent group t test
- more than 2 measures: RM ANOVA will be used - 15Two way ANOVA
