Research Hypothesis Presentation By: JOSINE L. CALIJAN

OBJECTIVE Lists research hypothesis (if appropriate) CS_RS12-If-j-8

Identify the kind of hypothesis. (Knowledge) Write a hypothesis. (Skills) Learning Objective: Realize the importance of hypothesis in research. (Affective)

ACTIVITY 1: MAKING PREDICTIONS Directions: The class will be divided into 5 groups. A picture will be given to each group, and they will answer the following questions. Afterwards, they will present their outputs.

Group 1

Group 2

Group 3

Group 4

Group 5

ANSWER THE FOLLOWING QUESTIONS: 1. Give at least 3 words that can describe the image? 2. Based on the picture, what do you expect to happen in the future?

Research Hypothesis

It is a tentative statement about the relationship between two or more variables. It is a specific and testable prediction on what you expect to happen with the variables in your study. Explanation

It is also described as an “educated guess” of what possibly the result would be of your research, which should be supported on existing theories and knowledge.

Types of Research Hypothesis

1. Simple Hypothesis 2. Complex Hypothesis 3. Empirical Hypothesis 4. Logical Hypothesis 5. Statistical Hypothesis 6. Null Hypothesis 7. Alternative Hypothesis

A simple hypothesis is a prediction of the relationship between two variables, the independent variable and the dependent variable. It shows a connection between one independent variable and a single dependent variable. Ex: The higher the poverty rate in society ( one independent variable ), the higher the number would be the out of school youth ( one dependent variable ). Simple Hypothesis

The complex hypothesis reflects the relationship between the independent variable and the dependent variable. It expresses a connection between two or more independent variables and two or more dependent variables. Ex: Eating more vegetables and fresh fruits ( independent variables ) leads to boost immune system and enhance blood circulation and digestion ( dependent variables ). Complex Hypothesis

Also called as the “working hypothesis.” It is presumed to explain certain facts and relationships of phenomena. It comes to life when the hypothesis is being put to test, using observation and experiment. Ex: Plants watered everyday grow faster than plants watered once a week. ( Here, trial and error are leading to a series of findings). Empirical Hypothesis

It expresses explanation with limited evidence that can be verified logically . It reflects a relationship of the variables which anchored based on logical phenomena. Ex: Tomato plants bear fruit faster in Earth than in Moon. ( Until we can test the soil and plant growth in Moon's ground, the evidence for this claim will be limited, and the hypothesis will only remain logical ). Logical Hypothesis

A statistical hypothesis is an analysis of a portion of a population . It can be verified statistically. Ex: A teacher assumes that 60% of his college students come from lower-middle class. Statistical Hypothesis

The null hypothesis is denoted with the symbol (Ho). It exists when you consider that there is no relationship between the independent and dependent variables or that there is an insufficient amount of information to claim a scientific hypothesis . Ex: There is no significant change in my health, whether I exercise every day or not. Null Hypothesis

An alternative hypothesis is denoted with the symbol (Ha). It is an alternate statement expressed to be tested to generate the desired output . To contradict a null hypothesis, you tend to seek an alternative hypothesis. Ex: There is a relationship between sleep deprivation and physical health. Alternative Hypothesis

Direction: Identify the Research Hypothesis from each of the following examples. Let Us Practice

Null Hypothesis 1. There is no relationship between the use of social media and the attention span of students in school.

Simple Hypothesis 2. The higher the unemployment rate, the higher will be the crime rate.

Statistical Hypothesis 3. 4 out of 5 dentists recommend a particular toothpaste for teeth whitening.

Alternative Hypothesis 4. There is a connection between anxiety and the academic achievement among Junior High School Students.

Complex Hypothesis 5. People with high-sugar diets and sedentary activity levels are more likely to develop anxiety and depression.

What is a hypothesis? What are the different types of hypothesis? Summary

Direction: Based on the given research title/problem, construct one hypothesis, identify its type, and write it in a manila paper. Group Activity: Writing a Hypothesis

Follow this format: Research Title: ____________________________ Type of Hypothesis: ________________________ Hypothesis:_______________________________
