This is conducted in order to discover new technologies, explore usability of existing materials or products, explain a certain phenomenon, develop products, apply science concepts and contribute to improve the quality of life.

• RESEARCH DESIGN

• QUALITATIVE RESEARCH

• EXPERIMENTAL RESEARCH

• ACTION RESEARCH

Which of the following is should not be considered in making a research methodology?

• How will the researcher find out the answer to scientific question?

• What materials (in what amount) tools, equipment, and apparatus will be used?

• Where and when experimentation will be done?

• Why and what are the variables in the study?

It is the specific procedures or techniques used to identify, select, process and analyze information about a topic.

• RESEARCH TOPIC

• RESEARCH VARIABLE

Which of the following best describes a research design?

• It provide enough details so that others can repeat the experiments following the methods written in the research paper.

• It is a complete sequence of steps or procedures that needs to be followed when obtaining the needed data during an investigation.

• It can manipulate or measure independent and dependent variables in studies to test cause-and-effect relationships.

• It is best to quantify measurements as much as possible, but accurate descriptive data throughout the experiment are helpful as well.

What are the characteristics of a research design?

• time-bound, specific, objectivity, attainable

• neutral, reliable, general, valid

• valid, specific, attainable, reliable

• time-bound, attainable, valid, neutral

What questions do you consider to recognize a dependent variable?

Choose 3 possible answer.

• Is this variable measured as an outcome of the study?

• Does this variable come before the other variable in time?

• Is this variable dependent on another variable in the study?

• Does this variable get measured only after other variables are altered?

What questions do you consider to recognize the independent variable?

• Does this variable come before the other variable in time?

• Is the variable manipulated, controlled, or used as a subject grouping method by the researcher?

• Is the researcher trying to understand whether or how this variable affects another variable?

• Does this variable get measured only after other variables are altered?

The treatment groups or trials that receive all the same conditions, except varying amounts or qualities of the independent variables. An important component of designing strong experiments is replication. What is replication?

• It is the number of treatment replications that you perform on experimental and control groups.

• It is the repetition in performing an experiment more than one.

• It represents a complete collection of every item that has the same characteristics as the individuals in the sample group.

• These are the factors that are kept the same for all groups to reduce the influence of additional variables.

This are the factors within an experiment that are kept the same for all groups or trials to reduce the influence of additional variables.

• CONTROL

• CONSTANTS

• VARIABLE

• POPULATION

The INDEPENDENT VARIABLE is the effect. Its value depends on changes in the dependent variable. This is the effect and the data that is recorded during the experiment.

• TRUE

• FALSE
