- 24. Statement of the Problem <ul><li>The problem was to determine the extent to which participants in outdoor recreation programs in college drop out and the reasons for their dropping out. </li></ul>
- 25. Steps to be Taken <ul><li>Delimit the problem </li></ul><ul><li>Rewrite the problem statement </li></ul><ul><li>Write the hypotheses/research questions </li></ul><ul><li>Identify assumptions & limitations </li></ul><ul><li>Develop operational definitions </li></ul>

- 27. Hypotheses <ul><li>Research hypothesis </li></ul><ul><li>Alternative hypothesis </li></ul><ul><li>Null hypothesis </li></ul>
- 28. Examples of Research Hypotheses <ul><li>If children are taught to read via whole language, then their reading comprehension will be higher. </li></ul><ul><li>If children watch 3 or more hours of TV per day, then their behavior on the playground will become more aggressive. </li></ul><ul><li>If children learn in small cooperative groups, then their social interactions will be more positive. </li></ul>
- 29. Form of Research Hypotheses <ul><li>IF, THEN: If young children take piano lessons, then they will have higher math aptitude 10 years later. </li></ul><ul><li>STATEMENT: Young children who take piano lessons will have higher math aptitude 10 years later. </li></ul><ul><li>QUESTION: Will young children who take piano lessons have higher math aptitude 10 years later? </li></ul>
- 30. Null Hypothesis & Statistics <ul><li>STATISTICAL QUESTION : How likely is it ( what is the probability ) that the actual findings in the sample would be obtained if the null hypothesis was true? </li></ul><ul><li>STATISTICAL ANSWER : p value </li></ul><ul><li>(probability value p =.05) </li></ul><ul><li>There is a 5% (5 in 100) chance that the actual findings in the sample would be obtained if the null hypothesis is true. </li></ul>
- 31. Examples <ul><li>RESEARCH : If children watch violent TV, then they will act more aggressively at recess. </li></ul><ul><li>ALTERNATIVE : Children prone to aggression simply watch more violent TV. </li></ul><ul><li>NULL : In a population of school-age children there is no relationship between TV violence and aggressive behavior. </li></ul>
