1.
To determine
To create: A null hypothesis, directional hypothesis and nondirectional hypothesis that explains the effects of attention span on out-of-seat classroom behavior.
1.
Expert Solution
Explanation of Solution
Answers will vary. One of the possible answers is given below:
Explanation:
Null hypothesis: The effect of attention span is measured by the attention span observation, spans consists same frequency of out of seat behavior as those with long attention span.
Directional: The effect of attention span is measured by the attention span observation, spans consists high frequency of out of seat behavior as those with long attention span.
Non directional: The effect of attention span in measured by the attention span observation, spans consists differ in frequency of out of seat behavior as those with long attention span.
