To check your understanding in the identification of the research problem, you have to go over the following activity. Profile of a Research Problem Task: Give the information in this profile and write a short article or essay about the research problem. A. Basic Facts 1. What is a research problem? 2. What are different features or characteristics of a good problem? (at least 5) 3. Cite at least 5 guidelines in the formulation of a research problem. B.

It also proposes a relationship between two or more variables (the independent and dependent variables) A good hypothesis should be simple, clear, specific and testable. Testing the hypothesis will enable the researcher to determine if the formulated hypothesis is accepted or rejected You may consider the following procedure or steps when formulating a hypothesis; 1. Read the literature and existing research 2. Identify the variables 3. Determine the relationship between variables 4. Determine how can they be measured 5. What are your theories 6. Formulate into hypothesis (phrase your hypothesis in 3 ways: null, alternative or in the cause and effect form (if -then form) Null hypothesis states that there is no significant difference between the results of variables being tested. It is usually the hypothesis the researcher will try to disprove (Ho) Alternative hypothesis states that there is a significant difference between the results of 2 variables being tested. This is simply the opposite of the null hypothesis (Ha) Cause and effect hypothesis states that in a certain condition (cause) is true, then the supporting observation (effect) occurs 6 What’s More Give what is asked for. 1. If the null hypothesis states that; “Attitude of children is not dependent on his /her birth order.”; alternative hypothesis states that: . 2. State the cause and effect hypothesis of the problem: Does an electric motor turn faster if you increase the current? . 3. If the alternative hypothesis states that; “The outdoor recreation program affects the behavior of youth at risk.”; null hypothesis states that: . 4. State the cause and effect hypothesis of the problem: Does the temperature of water affect the time it takes a sugar cube to be dissolved? . 5. If the null hypothesis states that;” Changing the intensity of light does not affect the growth rate of plants.”; alternative hypothesis states that: . 7 What I Have Learned 8 What I Can Do Hypothesis Formulation Formulate hypothesis (Ho-Ha) relevant to the following study. 1. BCNHS research students subjected the sweet potato noodles they formulated to a sensory evaluation test. The acceptability of the taste of the experimental and control noodles was evaluated by 30 panelists using a rating scale Ho: Ha: 2. Watching your grandmother bake breads, you learned that the dough of the bread rises because yeast acts on the sugar and releases gas. You wander whether the amount of sugar used will affect the size of the bread. Ho: Ha: 3. The helper noticed that when repairing instant coffee, he had difficulty dissolving the granules in water which was not hot enough. The helper wander if increasing the hotness of the water will also increase its ability to dissolve the granules. Ho: Ha: 4. The ability of a particular kind of fertilizer to increase the yield of yellow corn is under investigation. Four plots of yellow corn for experimentation are prepared. Ho: Ha: 5. Ten rabbits were used in investigating the effect of Dila-Dila wound ointment. Wounds from the hind legs of experimental and control rabbits were examined. Ho: Ha: 9 Assessment Identification 1. An educated prediction that provides an explanation for an observed event. 2. A hypothesis that says that there is no statistical significance between the two variables. 3. It provides the basis for the formulation of a hypothesis. 4. A type of hypothesis which follows the if -then form. 5. It is known as the hypothesis of significance or inequality. 6. It is conducted to test the hypothesis. 7. A hypothesis which only shows a relationship between one independent variable and one dependent variable 8. Proving your hypothesis as accepted or rejected using specific statistical tools only shows that the hypothesis is . 9. A hypothesis which is formulated based on specific questions. For numbers 10-15 identify whether the hypothesis is null or alternative. 10. Children who play violent video games does not behave aggressively. 11. Increasing the temperature of water affects the time it takes a sugar cube to dissolve. 12. Changing the height of the ramp does not affect the speed of the car going down the ramp. 13. School bullying affects the students’ academic performance. 14. People exposed to high level of ultra violet light have higher incidence of skin cancer. 15. Sleep deprivation shows no significant effect on work performance. 10 Additional Activities Part A: Alternative or Null Identify whether the hypothesis is null or alternative. Write Ho for null and Ha for alternative. 1. The number of hours spent by students playing computer games affect their academic performance in school. 2. Exposure to different temperature does not affect the germination of mango seeds 3. High school sex education has no effect on teenage pregnancy rates. 4. age Daily use of social media affects the attention span of those under 16 years of 5. School bullying does not affect the students’ academic performance. Part B: Formulation of Hypothesis Task: To formulate hypothesis based on the given problem.
