OVERVIEW OF SCIENTIFIC METHOD

• Science can be defined as a methodological andsystematic approach to the acquisition of newknowledge.

• It highlights some of the key differences between howscientists and nonscientists go about acquiring newknowledge.

• Specifically, rather than relying on mere casualobservations and an informal approach to learn aboutthe world, scientists attempt to gain new knowledge bymaking careful observations and using systematic,controlled, and methodical approaches.

46

Page 47: Dhaka University of Engineering and Technology …iqacduet.edu.bd/uploads/notices/merged_document_8.pdfsystematic approach to the acquisition of new ... distinguishes science from

• In addition, scientific knowledge is not based on the opinions,feelings, or intuition of the scientist.

• Instead, scientific knowledge is based on objective data that werereliably obtained in the context of a carefully designed research study.

• In short, scientific knowledge is based on the accumulation ofempirical evidence

• The defining characteristic of scientific research is the scientificmethod .

• First described by the English philosopher and scientist Roger Baconin the 13th century, it is still generally agreed that the scientificmethod is the basis for all scientific investigation.

• The scientific method is best thought of as an approach to theacquisition of new knowledge, and this approach effectivelydistinguishes science from non-science.

The Scientific Method

The development of the scientific method is

usually credited to Roger Bacon, a philosopher

and scientist from 13th-century England, although

some argue that the Italian scientist Galileo Galilei

played an important role in formulating the

scientific method.

Later contributions to the scientific method were

made by the philosophers Francis Bacon and

René Descartes.

48

Although some disagreement exists regarding thecharacteristics of the scientific method, most agree that itis characterized by the following elements:

1. Empirical approach2. Observations3. Questions4. Hypotheses5. Experiments6. Analyses7. Conclusions8. Replication

49

Page 50: Dhaka University of Engineering and Technology …iqacduet.edu.bd/uploads/notices/merged_document_8.pdfsystematic approach to the acquisition of new ... distinguishes science from

1. Empirical Approach• The empirical approach is an evidence-based approach that relies on

direct observation and experimentation in the acquisition of newknowledge.

• Scientific decisions are made based on the data derived from directobservation and experimentation.

• Contrast this approach to decision making with the way that mostnonscientific decisions are made.

• Example: Make decisions based on feelings, guesses, or “gut” instinctNOT necessarily based on data.

• The empirical approach, with its emphasis on direct, systematic, andcareful observation, is the best scientific method.

50

2. Observations

Observation refers to two distinct concepts being aware of the world around us and making careful measurements.

• Observations of the world around us often give rise to thequestions that are addressed through scientific research.

• keen eyes to the surroundings can often provide many ideas

Example:

Newtonian observation that apples fall from trees stimulated muchresearch into the effects of gravity

51

Page 52: Dhaka University of Engineering and Technology …iqacduet.edu.bd/uploads/notices/merged_document_8.pdfsystematic approach to the acquisition of new ... distinguishes science from

3. Questions

• Translating the research idea into an “answerable” question.

• It would obviously be a frustrating and ultimatelyunrewarding endeavor to attempt to answer anunanswerable research question through scientificinvestigation.

• It is therefore important to formulate a research questionthat can be answered through available scientific procedures.

52

Page 53: Dhaka University of Engineering and Technology …iqacduet.edu.bd/uploads/notices/merged_document_8.pdfsystematic approach to the acquisition of new ... distinguishes science from

4. Hypotheses

• Hypothesis is simply an educated and testable guess aboutthe answer to research question.

• It is often described as an attempt by the researcher toexplain the phenomenon of interest.

• A key feature of all hypotheses is prediction.

• Hypotheses are the researcher’s attempt to explain thephenomenon being studied that involve a prediction aboutthe variables being studied.

• These hypotheses can either be supported or refuted on thebasis of the data and analysis.

53

Page 54: Dhaka University of Engineering and Technology …iqacduet.edu.bd/uploads/notices/merged_document_8.pdfsystematic approach to the acquisition of new ... distinguishes science from

Two Types of Hypotheses:• Null hypothesis always predicts that there will be no

differences between the groups being studied.• Alternate hypothesis predicts that there will be a

difference between the groups.

Example: Exercise-Cholesterol• The null hypothesis would predict that the exercise group and

the no-exercise group will not differ significantly on levels ofcholesterol.

• The alternate hypothesis would predict that the exercise groupand the no-exercise group will differ significantly on cholesterollevels. 54

Page 55: Dhaka University of Engineering and Technology …iqacduet.edu.bd/uploads/notices/merged_document_8.pdfsystematic approach to the acquisition of new ... distinguishes science from

5. Experiments

• After articulating the hypothesis, the next step involvesexperiment.

• A key aspect of conducting a research study is measuring thephenomenon of interest (accuracy and reliability).

Example: Exercise-Cholesterol

• The researcher would collect data on the cholesterol levels of theparticipants by using an accurate and reliable measurementdevice.

• Then, the researcher would compare the cholesterol levels of thetwo groups to see if exercise had any effects.

55

Page 56: Dhaka University of Engineering and Technology …iqacduet.edu.bd/uploads/notices/merged_document_8.pdfsystematic approach to the acquisition of new ... distinguishes science from

6. Analyses

• After conducting the study and gathering the data, the nextstep involves analyzing the data, which generally calls for theuse of statistical techniques.

• The type of statistical techniques used by a researcherdepends on the design of the study, the type of data beinggathered, and the questions being asked.

• Statistics help researchers minimize the likelihood ofreaching an erroneous conclusion about the relationshipbetween the variables being studied.

56

Page 57: Dhaka University of Engineering and Technology …iqacduet.edu.bd/uploads/notices/merged_document_8.pdfsystematic approach to the acquisition of new ... distinguishes science from

7. Conclusions• After analyzing the data and determining whether to reject the

null hypothesis, the researcher is now in a position to drawsome conclusions.

• For example, if the researcher rejected the null hypothesis, theresearcher can conclude that the phenomenon being studiedhad an statistically significant effect (exercise had an effect onlevels of cholesterol).

• It is important that researchers make only those conclusionsthat can be supported by the data analyses.

• Going beyond the data is a cardinal sin that researchers must becareful to avoid.

57

Page 58: Dhaka University of Engineering and Technology …iqacduet.edu.bd/uploads/notices/merged_document_8.pdfsystematic approach to the acquisition of new ... distinguishes science from

8. Replication

• Replication essentially means conducting the same researchstudy a second time with another group of participants.

• The same researcher may attempt to replicate, or perhaps otherresearchers may undertake that task.

• Researchers should avoid drawing broad conclusions based onthe results of a single research study.

• In other words, the results of the research study were obtainedby chance, therefore, the results may not accurately representthe actual state of things.

58

Three general goals of scientific research:

• Description,

• Prediction, and

• Understanding/explaining

59

Most common types of research:

• Correlational research, and

• Experimental research

Page 60: Dhaka University of Engineering and Technology …iqacduet.edu.bd/uploads/notices/merged_document_8.pdfsystematic approach to the acquisition of new ... distinguishes science from

Correlational ResearchIn correlational research, the goal is to determine whether two ormore variables are related.

Example:Whether age is related to weight. A researcher may discover that age is indeedrelated to weight because as age increases, weight also increases. If thecorrelation between two variables is strong enough, knowing about onevariable allows a researcher to make a prediction about the another variable.

Cause-and-Effect:

• A correlation or relationship between two things does notnecessarily mean that one thing caused the other.

• To draw a cause-and-effect conclusion, researchers must useexperimental research.

60

Page 61: Dhaka University of Engineering and Technology …iqacduet.edu.bd/uploads/notices/merged_document_8.pdfsystematic approach to the acquisition of new ... distinguishes science from

Experimental ResearchExperimental research involves comparing two groups on one outcome to test somehypothesis.

Example: The effects of a New Medication on Headaches

• The researcher would randomly divide a group of people with headaches intotwo groups.

• The experimental group, would receive the new medication being tested.

• The control group, would receive a placebo medication.

• Besides receiving the different medications, the groups would be treated exactlythe same so that the research could isolate the effects of the medications. Afterreceiving the medications, both groups would be compared to see whetherpeople in the experimental group had less headache than people in the controlgroup.

• If people in the experimental group had fewer headaches than people in thecontrol group, the researcher could conclude that the new medication reducesheadaches.

Qualitative vs. Quantitative

70

QuaNtitative ParadigmGenerally attempt to quantifyvariables of interest. Questionsfrequently address “how well orhow much.”

N for numbers Statistical Quantifiable

QuaLitative Paradigm

“there are times when we wish toknow not how many or how well,but simply how.”

Descriptive

Numbers not the primary focus

Interpretive, ethnographic, naturalistic

Keep in Mind & Be Critical

• No study is perfect

• “All data is dirty is some way or another; research is what you do with that dirty data”

• “Every statistic is a way of summarizing complex information into relatively simple numbers.”

• How did the researchers arrive at these numbers?

• Who produced the numbers and what is their bias?

• Is the statistical result interpreted correctly?

• Measurement involves making choices
