Answer explanation

There are 4 levels of measurement - nominal, ordinal, interval, and ratio

measurement of variables

• assessment

• testing

• error

• reliability

Answer explanation

Testing was defined as "the process of measuring...variables by means of devices or procedures designed to obtain a sample of behavior" by Cohen, Swerdlik, and Phillips (2002)

gathering and integrating data to make educational evaluations

• assessment

• testing

• reliability

• measurement

Answer explanation

Cohen, Swerdlik, and Phillips (2002) defined assessment as "the gathering and integration of...data for the purpose of making...an educational evaluation, accomplished through the use. of tools such as tests, interviews, case studies, behavioral observation, and specially designed apparatus and measurement procedures"

the difference between true scores and observed scores

• error

• reliability

• validity

• measurement

Answer explanation

tests should be developed to have small amounts of error

the consistency or stability of test scores

• validity

• assessment

• reliability

• measurement

Answer explanation

reliable tests will give similar results on every time they are administered

the accuracy of the inferences, interpretations, or actions made on the basis of test scores

• validity

• reliability

• error

• assessment

Answer explanation

validity may be affected by the presence of a systematic error that occurs every time a test is used

Identify the data set's level of measurement:

The amount of time it takes a student to complete a task

• nominal

• oridinal

• interval

• ratio

Answer explanation

This data can be ordered and has a true zero, therefore it is a ratio level measurement

Identify the data set's level of measurement:

You collect the student id number for each participant in your study

• nominal

• ordinal

• interval

• ratio

Answer explanation

Although this data is numerical, this data would be qualitative, because the numbers have no mathematical value, therefore the measurement is at a nominal level

Identify the data set's level of measurement:

Your students rank their learning activities as 1st, 2nd, and 3rd favorite

• nominal

• ordinal

• interval

• ratio

Answer explanation

These values can be ordered, but the differences between the rankings is not meaningful, making this an ordinal measurement

Identify the data set's level of measurement:

You ask teachers to record the time they leave school each day

• nominal

• ordinal

• interval

• ratio

Answer explanation

Because the difference between each hour is the same, but there is not true zero, this would be a measurement at the interval level
