Regardless of whether H1 is directional or nondirectional, when evaluating H0 we always assume chance is responsible for the differences in results between conditions.
Indicate whether the statement is true or false
Question 2
If the results of an experiment allow rejection of the null hypothesis, _________.
a. the effect of the independent variable must be large.
b. similar results are likely to occur if the experiment is repeated
c. the experiment proves that H0 is false.
d. the effect of the independent variable must be large and the experiment proves that H0 is false.
e. similar results are likely to occur if the experiment is repeated and the experiment proves that H0 is false.
Directional selection.
Three principle forms of natural selection: (a) stabilizing selection, (b) directional selection, an
Directional drilling taps multiple oil deposits
Directional selection pushes a phenotype one way or another.
For the circuit in Figure 1, assume ideal diodes. The peak inverse voltage is approximately
Directional selection
