14 important questions on Book page 5-10
Z score/ standard score
What are the two steps for score location?
2. We use a table of areas for the standard normal distribution to look up the % of scores that fall below that z score
How does a normal distribution/ Gaussian distribution appears in a histogram?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What do we obtain when we convert an x score into a z score?
When are values far or very far from the mean?
Very far= below z=-3.00 and above z=3.00
In what three areas can normal distribution be divided?
2. 95% of the area in the centre
3. 2.5% of the area above +z, the ''upper tail''
What does an empirical example illustrates?
When do hypothesis correspond to equations?
What two hypothesis are needed for NHST?
2. Alternative hypothesis (Halt, H1)
What are alternative hypothesis?
What do we call tail areas that lie beyond specific values t?
For what can the tables of the t distributions can be for?
What three things do we need to know to define the reject regions for values of t?
2. Choice of alpha
3. Sample df (N-1)
What are the reject rules of obtained p value, using alpha=0.05?
2. If p>.05 do not reject
