is the ability of the instrument to measure what its purpose to measure. Data is valid when it measures or describes what it set up to measure or describe.

validity

-analysis of whether the instrument is using a valid scale -intuitive judgment -measuring what its supposed to primarily based upon the logical link between the questions and the objectives of the study

face validity

not to undertake any data collection or analysis methodology that is more complex or expensive than is necessary

keeping things simple

is the extent to which similar results are obtained on two separate administrations

stability

The same test given to the group of respondents twice. The scores in the first are correlated to the scores in the second

test-retest

measures the consistency of results when you repeat the same test on the same sample at different point in time

test-retest reliability

-study weather they are able to elicit the necessary information -The items and questions cover the full range of the issue or attitude being measured

content validity

refers to how well a survey, questionnaire, or test actually measures what you want it to measure. determining how all items on the test relate to all other items.

internal consistency reliability

The extent that its items measure the same trait

internally consistent

-One of the oldest methods for assessing internal consistency -this approach items on a scale are split into two groups and scored independently, scores on the two half are then used to compute a correlation coefficient

split-half technique

is the ability of an instrument to identify a case correctly that is to screen in or diagnosis a condition correctly -true positive

sensitivity

-is the instruments ability to identify non cases correctly that is the screen out those without the condition correctly -true negatives

specificity

-refers to the consistency and stability of the results -a reliable instrument deals the same rank for each individual who take the test or more than once

reliability

the greater the degree of consistency and stability in an instrument, the greater the blank

reliability

it involves establishing that the results of a qualitative research or credible or believable from the perspective of the participant in the research

credibility

split-half reliability involves what

SARF

as the mood of respondent good change from one interview to another, so could the mood, motivation, and interaction of the interviewer which could affect the responses given by the respondents

the interviewer's mood

in an interview situation, The interaction between the interviewer and the interviewee can affect responses significantly.During the repeat interview responses may be different due to changing interaction which could affect reliability

the nature of interaction

when a research instrument is used to measure attitudes towards an issue some respondents after having expressed their opinion, may feel that they have been either to negative or two positive towards the issue.

the regression effect of an instrument

what should be found in the discussion of the formulation of instrument of the study?

TCRD

this refers to the degree to which the results of qualitative research can be generalized or transferred to other contexts or settings

transferability

in the framework suggested by Guba and Lincoln, it is concerned with whether the researcher would obtain the same results if he observes when the same thing twice

dependability

refers to the degree to which the results would be confirmed or corroborated by others

confirmability

it deals with the measures that can be administered and validated at the same time

concurrent

a slight ambiguity in the wording of questions or statements as respondents may interpret that questions differently at different times resulting in different responses

the wording of questions

in the case of an instrument being used in an interview any change in the physical setting at the same time of the repeat interview may affect the responses given by the respondent

the physical setting

a change in respondents mode when responding the questions or writing answers in a questionnaire can change in effect his responses

the respondent's mood

what are the factors affecting the reliability of a research instrument

WPRINT

is the consistency with which it measures the target attribute

reliability

The three key aspects are

stability, internal consistency, equivalence

the principles in data collection

KPAE

estimated by having two or more trained observers to watch an event simultaneously and independently recording data according to the instruments instruction

interrater reliability

involves the assignment of numbers to represent the amount of an attribute present in an object or person using a specified set of rules

measurement

refers to how well the test predicts some future behavior of the examiners

predictive

-whether the test corresponds with its theoretical construct -extend to which it is consistent with theoretically derive hypothesis

construct validity

an expression of how scores from tests are correlated with an external criterion

criterion related validity

what are the types of validity
