To obtain more meaningful statistical result, the data must come from a large sample size.

The determination of the different kinds of physical activities and how often high school students do it during the quarantine period.

Data is numerical, which makes presentation through graphs, charts, and tables possible and for better conveyance and interpretation.

How does the parent’s academic achievement affect the children obesity?

What does the researcher use to allow the researcher to collect data from a large sample size efficiently.

why does quasi experimental has a lesser validity

Why is quantitative research scientific

Characteristics of quantitative research

Conclusive establishment of cause and effect

Example of statistical analysis

Numerical and quantifiable data can be used to predict outcomes

Example of rating scale

Quantitative Research can be replicated or repeated

It does not provide comprehensive explanation of human experiences

Meaning of ex post facto

Is used to describe a particular phenomenon by observing it as it occurs in nature.

Some information cannot be described by numerical data such as feelings, and beliefs

The independent variable is identified but not manipulated

There is no experimental manipulation and the researcher does not start with a hypothesis.

The use of a statistical tools give way for a less time- consuming data analysis.

Why is data in correlational design collected by observation

The research design is rigid and not very flexible

Data is taken and analyzed objectively from a sample as a representative of the population, making it more credible and reliable for policymaking and decision making.

Validity and reliability can be established

There is no experimental manipulation in this design.

Very objective

Findings are generalizable to the population

What are the kinds of quantitative research

What would be the next once data is collected

Is any existing or observable fact or situation that we want to unearth further or understand.

Identifies the relationship between variables.

The goal of this research is only to describe the person or object of the study.

The participant are limited to choose only from the given responses

Therelationship between the amount of physical activity done and student academic achievement.

Fast and easy data analysis using statistical software

Used to establish the cause and effect of an variable

The group exposed to treatment (experimental) are compared to the group unexposed to treatment (control)

looks at a possible causes of an already occurring phenomenon

A large sample size makes data colleection more costly

Depending on the type of data needed, collection can be quick and easy. Quantitative research uses standardized research instruments that allow the researcher to collect data from a large sample size efficiently. For instance, a single survey form can be administered simultaneously to collect various measurable characteristics like age, gender, socio-economic status, etc.

It lacks the necessary data to explore a proble or concept in depth

Uses scientifically collected and statistically analyzed data to investigate observable phenomena.

Data taken from a sample can be applied to the population if sampling is done accordingly, i.e., sufficient size and random samples were taken.

Used to established cause and effect relationship of two or more variables

Data gathering and analysis of results are done accurately, objectively, and are unaffected by the researcher’s intuition and personal guesses.

is used to investigate a possible relationship between previous events and present conditions.

Provides a more conclusive result because it uses random assignment of two or more variables

The Quantitative method can be repeated to verify findings enhancing its validity, free from false or immature conclusions.
