A branch of Mathematics that deals with scientific collection, presentation, analysis, and interpretation of numerical data in order to obtain useful and meaningful information.

Values that the variable can assume.

Consist of all subject that are being studied.

collection of data values

A group of subjects selected from a population

Measure used to describe the population.

A type of Statistics that consist of collection, organization, summarization and presentation of data.

Quantitative Data that are countable using a finite count, such as 0, 1, 2 and so on.

Type of Data where variables are placed into distinct categories according to some characteristic or attribute. It consist of labels, category names, and such for which representation on a numerical scale is not naturally meaningfully.

Characteristics or attribute that can assume different values.

Measure computed from sample data.

A person who is trained in collecting numerical information

A set of procedures and rules for reducing large masses of data into manageable proportions allowing us to draw conclusions.

Data that can be numerical and can be ordered.

Quantitative Data that can take on any value within a range of values on a numerical scale.

Lowest level of data

Level that characterized by data consist of names, labels or categories only and cannot be arrange in ordering scheme.

Highest level of measurement.

Characterized by data that can be ranked.

All of the subjects of interest.

The process of selecting the individuals from the population that makes up the sample

Nonstatistical Sampling which is collected in the most convenient manner for the Researcher.

items of the sample are chosen based on known or calculable probabilities

Divide population into subgroups.

Randomly select one individual from the 1st group.

Which is true about "Why sample?"
