Science of collecting, organizing, summarizing and analyzing information to draw condusions or answers question -It provides procedure in data collection, presentation, organization and interpretation to have a meaning ful idea.

According to Meriam Webster, it is factual information (such as measurements or statistics) used as a basis for reasoning, discussion or calculation.

basically consists of organizing and summarizing data. - describes data through numerical summaries, tables and graphs.

logical process that involves generalizing from a sample to the population from which the sample was selected and assessing the reliability of such generalizations. Comparison/ Venn diagram

consists of ALL the members of the group about which you want to draw a condusion

numerical index describing a charactenstic of a population

Come from a onginal source and are intended to answer a specific research question. can be taken by interview, mait in questionnaire, survey or experimentation

data taken from prenoudy recorded data internet can also be taken electronically for instance via websites.

process of choosing/selecting individuals from population to sample.

using an objective chance of mechanism to choose sample the probability of selection for a sample is KNOWN

there is an equal chance of selection for the samples ex: use of lottery or via random names fishball method wheel of names

•System or pattem on choosing samples

dividing the population to non overlapping groups called strata choosing sample from each strata.

dividing population into non-overlapping groups then randomly select a group and choose all samples within that group.

dividing population into non-overlapping groups then randomly select a group and choose all samples within that group.

sampling method where no objective chance mechanism is used. We choose sample by convenience or hazardly or taking volunteers. probability of selection is UNKNOWN.

Sampling-choosing sample that are Conveniently available to you.

identifying a specific anteria or qualification before an individual can be a sample

Sampling-non probability counterpart of STRS

relying on samples to obtain more samples.

asking samples to volunteer to be part of the study.
