statts

consists of conducting studies to collect, organize, summarize, analyze, and draw conclusions.

is a characteristic or attribute that can assume different values

are the values (measurements or observations) that the variables can assume.

Variables whose values are determined by chance are called?

A collection of data values forms a

Each value in the data set is called a _ or _?

consists of the collection, organization, summarization, and presentation of data.

consists of all subjects (human or otherwise) that are being studied.

is a subgroup of the population.

consists of generalizing from samples to populations, performing hypothesis testing, determining relationships among variables, and making predictions.

are variables that can be placed into distinct categories, according to some characteristic or attribute.

are numerical in nature and can be ordered or ranked.

assume values that can be counted.

can assume all values between any two specific values. They are obtained by measuring.

classifies data into mutually exclusive (non overlapping), exhausting categories in which no order or ranking can be imposed on the data.

classifies data into categories that can be ranked; precise differences between the ranks do not exist.

ranks data; precise differences between units of measure do exist; there is no meaningful zero.

possesses all the characteristics of interval measurement, and there exists a true zero. In addition, true ratios exist for the same variable.

what are the four methods of sampling?

what are the types of statistics

4 levels of Measurement?

are selected by using chance methods or random numbers.

are obtained by numbering each value in the population and then selecting the kth value.

are selected by dividing the population into groups (strata) according to some characteristic and then taking samples from each group.

are selected by dividing the population into groups and then taking samples of the groups.

_ and _ make numerical computation easier.

is the organization of raw data in table form, using classes and frequencies?

data in original form are called?

each raw data is placed into qualitative and quantitave category called?
