target population | population to which researcher would like to study |
accessible population | available population |
probability sampling | are techniques to help select sample |
simple random sampling | quantitative select a sample in such a way that all individuals in the defined pop have equal and independent chance of selection for the sample |
stratified sampling | quantitative way to guarantee desired representation of relevant subgroups within the sample. some groups are subdivided into subgroups known as strata |
proportional stratified sampling | quantitative process of selecting a sample in such a way that identified subgroups in a pop |
cluster sampling | quantitative intact groups, not individuals are randomly selected |
systematic sampling | quantitative a sample in which every certain number is used. |
sampling error | chance variation |
sampling bia | sampling error that is the fault of the researcher. |
nonprobability sampling (nonrandom sampling) | quantitative process of selecting a sample using a technique that does not permit the researcher to specify the chance. |
convenience sampling | quantitative referred to as accidental sampling or haphazard sampling, process of whoever happens to be available at the time |
purposive sampling | quantitative referred to as judge ment sampling process of selecting a sample that is believed to be representative of a given pop |
quota sampling | quantitative process of selecting a sample based on required exact numbers of individuals with same characteristics |
qualitative sampling | selecting a small number of individuals for a study |
examples of qualitative sampling | intensity, homogeneous, criterion,snowball, random purposive sampling |
construct | abstraction that can not be observed directly; concept invented to explain behavior |
variable | placeholder that can assume any one of a range of value |
measurement scale | system for organizing data that can be inspected, analyzed, and interpreted |
nominal variable | categorical variable, values include two or more named categories (ex: gender, employment, marital status) |
ordinal variable | rank order, unequal units (ex: reading groups based on scores) |
interval variable | characteristics of nominal and ordinal variables but values represent = intervals. NO true zero point.(ex: achievement, aptitude, motivation, and attitude tests |
ratio variable | properties of the previous three types + measurement scale has a true zero point. (ex: height, weight, time, distance, and speed) |
quantitative variables examples | range from low to high or less to more. Ordinal, interval and ratio because they describe performance( ex:test scores, heights, speed, age, and class size) |
qualitative variable examples | nominal or categorical provide information, nominal variables permit persons (ex:eye color, religion, gender, political party) |
dependent variable | variable hypothesized to depend on or to be caused by another variable. Also called criterion, effect, outcome or post test. |
independent variable | called experimental, manipulated, the cause, or the treatment, hypothesized cause of the dependent. |
test | gather information about people's cognitive |
cognitive characteristics | mental characteristic related to intellect ex: achievement |
affective characteristic | mental characteristic related to emotion ex: attitude |
standardized test | administered, scored, and interpreted in the same way no matter where it is given ex: SAT, ACT, Iowa tests, Stanford Achievement test etc. |
assessment | broad term that uses the entire process of collecting, synthesizing, and interpreting information whether formal, informal, numerical or textual. |
performance assessment | authentic or alternative assessment, type that emphasizes a students process ex: lab demonstration, debate, essay, science fair project |
raw score | value a person answered correctly on an assessment |
norm referenced scoring | assessment compared to performance of others |
criterion reference scoring | individual performance on an assessment compared to predetermined standard. |
self reference scoring approach | measuring how individual performance on a single assessment changes over time |
cognitive test | measures intellectual process like thinking, memorizing, problem, solving, analyzing, reasoning, and applying information. |
achievement test | measures an individual current proficiency in given areas of knowledge or skill. ex: California achievement test, Stanford, TerraNova, Iowa test. |
diagnostic test | multiple scores identification of a student's weak and strong areas within the subject area |
aptitude test | predict how well an individual is likely to perform in a future situation. |
affective test | assessment designed to measure affective characteristics ex: mental characteristics related to emotion such as attitude, interest and value. |
attitude scale | measures what individual believes, perceives, or feels about self, other, activities, institutions or situations. ex: likert scales, semantic differential scales, rating scales, Thurstone scale, Guttman scales. |
Likert Scales | individual to respond to a series of statements by indicating whether he or she strongly agrees, agrees, undecided, disagrees, or strongly disagrees. |
semantic differential scales | individual to indicate his or her attitude about a topic fair to unfair |
rating scale | respondent's attitudes toward self, others, activities, institutions or situations. |
Thurstone and Guttman Scales | select from a list of statements that represent different points of view on a topic |
validity | degree to which a test measures what it is supposed to measure and appropriate interpretation of scores. |
content validity | degree to which test measures intended content area. |
item validity | whether the test items are relevant to the measurement of the intended content area. |
sampling validity | how well the test samples the total content area being tested. |
Criterion related validity | relating performance on test to performance on second test. ex pre and post test |
concurrent validity | degree to which scores on one test are related to scores on a similar ex: correlation between scores on the test under study (new test) and scores on some other established test (grade point average) |
predictive validity | degree which a test can predict how well an individual will do in a future situation. ex: algebra aptitude test at the start of school can predict which students will perform well or poorly |
construct validity | most important form of validity, it asks the fundamental validity ? underlie the variables that researchers measure |
consequential validity | concerned with the consequences that occur from test. looking at this helps to identify tests that may be harmful to students, teachers, and other |
face validity | degree to which a test appears to measure what it claims to measure |
reliability | degree to which the test consistently measures whatever it is measuring. Factor that threatens validity |
five types of reliability | stability, equivalence, equivalence and stability, internal consistency, scorer/rater |
stability (test-retest) | stability of scores over time, give one group the same test at two different times and correlate the scores. |
equivalence (alternative forms) | relationship between two versions of a test intended to be =, give alternative test forms to a single group, and correlate the two scores |
equivalence and stability | relationship between equivalent versions of a test given at two different times, give two alternative tests to a group at two different times, correlate the scores |
internal consistency | the extent to which the items in a test are similar to one another in content, give tests to one group and apply split half Kuder-Richardson or Crondbach alpha to estimate the consistency of test items. |
scorer/rater | the extent to which independent scores or a single scorer over time agree on the scoring of an open-ended test. |
standard error of measurement | estimate of how often one can expect errors of a given size in a individual test score |
