COGNITIVE practical Flashcards
what where the ethical principles we followed
consent, right to withdraw
explain the aim of the practical
- partially replicate Glanzer’s study
- see if participants recall more words from the start of a list using the LTM compared to the middle
what was the IV and DV
IV- whether words are at the beginning or the middle of the list
DV- how many of the first 9 words are recalled and how many of the middle 9 words are recalled
write a null hypothesis
there will be no significant difference between how many words are recalled (out of 90) from the beginning of the list compared with the middle of the list, and any difference will be due to chance.
what was the sampling technique and the group design
opportunity sample with a repeated measures design
what data was collected and what average was used
ordinal data - median
which statistical analysis method was used
Wilcoxon signed rank test
why was this statistical analysis used
ordinal data collected and repeated measures design used
how do you use the statistical analysis test
1) find the difference from left to right of the results
2) rank the difference by using the mean of the ranks
3) rank if positive and rank if negative (two separate columns)
which data found after finding positive and negative ranks is used as the calculated value
the smallest digit out of the two
which table do you use
0.05 level of significance and will say in the question if it is a two or one-tailed hypothesis
how can you tell whether it is significant
it will say under the table - so look
