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

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

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

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

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

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

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

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.

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.

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.

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

Quantitative Research can be replicated or repeated

Findings are generalizable to the population

Conclusive establishment of cause and effect

Numerical and quantifiable data can be used to predict outcomes

Fast and easy data analysis using statistical software

Very objective

Validity and reliability can be established

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

It does not provide comprehensive explanation of human experiences

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

The research design is rigid and not very flexible

The participant are limited to choose only from the given responses

A large sample size makes data colleection more costly

What are the kinds of quantitative research

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

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

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

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

Identifies the relationship between variables.

Why is data in correlational design collected by observation

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

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

Meaning of ex post facto

There is no experimental manipulation in this design.

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

looks at a possible causes of an already occurring phenomenon

Used to establish the cause and effect of an variable

why does quasi experimental has a lesser validity

The independent variable is identified but not manipulated

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

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

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