Data

consist of information coming from observations, counts, measurements, or responses. the singular for data is datum.


Statistics

is the science of collecting, organizing, analyzing, and interpreting data in order to make decision.


Population

is the collection of all outcomes,responses, measurements, or counts that are of interest.


Sample

is asubset of a population.


parameter

is a numerical description of a population characteristic.


statistic

is a numerical description of a sample characteristic.


Descriptve Statistice

is the branch of statistics that involves the organization display of data.


Inferential Statistics

is the branch of statistics that involves using asample to draw conclusions about a population. A basic tool in the study of inferential statistics is probability.


Qualitative data

consist of attribustes,labels,or nonnumerical entries.


Quantitative data

Consist of numerical measurements or counts.


Nominal level of measurement

are qualitative only. Data at this level are categorized using names, labels,or qualitative or quantitative. data at this level are categorixed using names, labels, or qualities. No mathhematical computations can be made at this level.


ordinal level of measurement

are qualitative or quantitative. Data at this level can be arranged in order,but differences between data entries are not meaningful.


Intervall level of measurenment

are quantitative. The data can be ordered,and you can calculate meaningful differences between data at the interval level. wotj tje added property that a zero entry is an inherent zero.


ratio level of measurement

are similar to data at the interval level, with the added property that a xero entry is an inherent zero. A ratio of two dat values can be formed so one data value can be expressed as a multiple of another.
