    1. more negative

      shouldn't this be more positive? (the CI is 0,043; 0,302) And the unstandardized regression coefficient is 0,172.

    2. 0.12 to 0.34 point

      Waarom noem je hier twee keer de Confidence interval en niet een keer de ongestandaardiseerde regressiecoefficient (van 0,23)?

    1. BY status3 exposure3

      Does this sequence matter? The assignment doesn't really say what is the moderator en what the predictor?

    2. /PRINT=HOMOGENEITY DESCRIPTIVE

      Maakt deze volgorde uit in de syntax? (bij mij staat er eerst descriptive en dan homogeneity)

    1. Squaring, summing, and averaging the solid red arrows (within-groups differences) yields the within-groups variance

      Can you explain this? Or can you give an example?

    1. (Standard) normal distribution one or two means > 100 t distribution one or two means each group > 30

      What is the difference between these two? When does your sample have to contain >100 people (because when you test 2 means you have 2 groups and do a t-test right, so each group has to be over 30 so a minimum of 60?)

    1. 6.3.2 Data generating process

      In test exam 1 there is a question about this, but I didn't understand it and reading this did not make it any clearer.. Are there other ways to grasp this?

      Hoe krijg ik dit in mijn syntax erbij? Zodat je niet die hele tabel Candy weight krijgt? En is dit belangrijk voor in het tentamen?

    1. We have learned that larger samples have smaller standard errors (Section 3.3.1). Smaller standard errors yield larger test statistic values and larger test statistics have smaller p values. In other words, a test on a larger sample is more often statistically significant.

      Why do larger samples have smaller standard errors?

      Question regarding bonus point. It says the following in the syllabus: "Students earning less than half of all points receive a fraction of the full bonus point that corresponds to the proportion of all points awarded.". How exactly is that calculated?

    1. ownload the data set candies.sav and use SPSS to apply a Fisher-exact test to the association between candy colour and candy stickiness

      Wat is het verschil tussen een Fishers exact test en een Chi-kwadraat test?

    1. Download the data set candies.sav and use SPSS to bootstrap the t test on average weight of yellow and red candies (the example above). The test is available in the Analyze>Compare Means menu.

      Wanneer gebruik je one sampled t test, independent t-test en paired sampled t-test? (wat is het verschil tussen deze)

      Q&A

      Could you go through the equation, where do the values come from, how to work with it, maybe an example question? Thanks!
