Key point

Basic research

Applied research

DefinitionIt’s like learning just to satisfy your curiosity.This is like inventing a new tool to fix a specific problem.
NatureVery open and general.Targeted and practical.
PurposeTo discover new things without thinking about solving a specific problem.To create solutions or improve how things work.
UserScientists and researchers who are exploring fundamental conceptsCompanies, engineers, and professionals looking to address specific challenges.
FormalityIt can be quite formal with structured methods.More like everyday observations, not too strict.
Key point

Qualitative research

Quantitative research

Definition Qualitative research is exploring ideas and experiences in detail. Quantitative research is numbers to find answers.
Nature Its focus on the actual quality of Question and answer. Its focus on number of questions and answer.
Purpose To get actual behaviors, feeling and motivation. To get theoretical test or hypotheses Test of data.
User Researchers studying human behavior, like psychologists, sociologists, and marketers. Scientists, economists, and researchers who need precise measurements to test ideas.
Formality Its provide less formal structure. Its provide good formal strure.
Key point

Survey

Experiments

Definition Gathering information by asking people directly is called survey. Testing something to see what happen is called experiments.
Nature Direct collect from customer. Direct result to see effect.
Purpose To understand consumer properly. To understand result for reuse.
User Businesses, governments, and researchers who want to know about people’s opinions or behaviors. Scientists and researchers looking to discover or prove cause-and-effect relationships.  
Formality It can run on question base. It can run by structure base.

Key point

Cross-sectional

Longitudinal study

Definition

cross-sectional is like big photo that’s looks every thinks at a moment.longitudinal study is like series that’s shows change over a long period.
NatureOne capture of different thinksOne subject changes at different time
PurposeGathering current data from various sources.Gathering data from taking day, month and years.
UserResearcher who use quicklyResearcher who use actual changes
FormalityLess formalMore formal

Key point

Primary data

Secondary data

DefinitionRaw data collected from survey, interviews and experiment is called primary data.Collected data as like report, newspaper or books is called secondary data.
NatureFree and original dataAlready collected and repurpose
PurposeTo get original data from sourceTo save money & time
UserResearcher who find specific dataResearcher who use data so fast.
FormalityGood and formalLess formal

Key point

Mean deviation

Standard deviation

DefinitionMean deviation tells you the average distance.Standard deviation gives more weight to bigger differences.
Naturediffers from the averageSquare the difference
PurposeTo get simple ideaTo get clear picture of data
UserWho get basic dataWho get specific and financial data.
FormalityIt’s less formalMore formal

Key pointSampling ErrorStandard Error

Definition

Difference between sample and actual data is called sampling error.Difference between sample mean and population mean is called standard error.
NatureIts show Randomness selecting a sampleIts show sample vary from one to another.
Purposeits provide accuracy of sample  estimationIt provides reliability of sample estimation
UserSurvey designer consider this errorResearchers, statisticians, and analysts consider this error.

Differences between technical and popular reports based on five key point are as follows:

Key pointTechnical ReportPopular Report
DefinitionA technical report is a document that explains detailed information on a specific topic.A popular report is a document that presents complex information in a simple and clear way for the general public to understand.
NatureThis report describe the Process of research.This report describe the solution & findings.
PurposeIt’s make to use professional field.It’s make to simplify complicated subjects so that anyone can understand them.

FormalityThis report make perfect official & formal.

This report is not perfect official & formal.

 This table highlights some important point of Difference Technical Report and Popular Report.

Key point

Parametric

Non- parametric

DefinitionParametric test is called  statistical tests.Non-parametric test is statistical test but not assumption about the population of distribution.
NatureNumerical data.distribution-free  data
Purposetest relationships between to variablesNo relation between two variables
UserResearchers and statisticians use parametric tests when data meet the required assumptions.Researchers, particularly in fields where data may not meet parametric assumptions, employ non-parametric tests.
FormalityParametric tests are considered more formalNon-parametric tests are less formal

Key pointHypothesisNull hypothesis
DefinitionA research hypothesis is an educated guess predicting the relationship between variables or the expected outcome of a studyA null hypothesis is a statement suggesting that there is no significant relationship or effect between variables in a study.
Nature

proposing an anticipated result.

 

No effect, difference or relationship.

 

Purposetest relationships between to variablesNo relation between two variables
UserResearchers, scientists, and academics create research hypotheses to direct their research.Researchers and statisticians use null hypotheses to evaluate the significance of research findings.
FormalityResearch hypotheses are formal, specific.

Null hypotheses are less formal and specific.

 

Key point

Correlation

Regression

DefinitionCorrelation measures the strength and direction of the relationship between two variables.

Regression predicts the value of one variable based on the value of another variable.

 

Natureit indicates how changes in one variable are associated with changes in another variable.

It models the relationship between variables by fitting a line or curve to the data.

 

PurposeCorrelation helps to understand the extent to which variables are related to each other.

Regression helps to understand how changes in one variable affect another and to make predictions.

 

UserResearchers, analysts, and scientists use correlation to explore connections between variables.Researchers, economists, and analysts use regression for predictive modeling and understanding causal relationships.
Formality

correlation coefficients ranging from -1 to 1.

 

Regression analysis can be more complex.

Key pointPropositionHypothesis
Definition

A proposition is a statement or idea put forward for consideration or discussion.

 

A hypothesis is a testable prediction or statement about the relationship between variables in research.

 

Nature

It can be a claim, assertion, or proposal that may or may not be based on evidence.

 

It is based on existing knowledge, theory, or observation and is subject to empirical testing.

 

Purpose

Propositions aim to express a point of view, persuade, or stimulate further inquiry.

 

Hypotheses guide research by proposing expected outcomes or relationships to be investigated.

 

User

Writers, debaters, and policymakers often use propositions to present arguments or ideas.

 

Scientists, researchers, and scholars formulate hypotheses to structure their studies.

 

FormalityPropositions can range from informal statements to formal propositions in debates or legal contexts.Hypotheses are formal statements that are specific, testable, and often derived from existing theory or empirical evidence.
