Where observer scores do not significantly correlate then reliability can be improved by: Training observers in the observation techniques being used and making sure everyone agrees with them. Ensuring behavior categories have been operationalized. This means that they have been objectively defined.External reliability
Such reliability issues can be improved by standardising procedures (i.e. making sure that procedures are carried out the same way each time), for instance by implementing interviewer training, and/or practice through pilot studies.

How can the reliability of an experiment be improved?
Results are RELIABLE if
the experiment is repeated the results are the same (within an acceptable margin of error). Repetition will only determine reliability it will NOT improve it. Reliability can be improved by carefully controlling all variables (except the experimental variables!!)
How can improve the reliability and validity?
You can increase the validity of an experiment by controlling more variables, improving measurement technique, increasing randomization to reduce sample bias, blinding the experiment, and adding control or placebo groups.
What is meant by inter observer reliability?
Inter-rater reliability, which is sometimes referred to as interobserver reliability (these terms can be used interchangeably), is the degree to which different raters or judges make consistent estimates of the same phenomenon. For example, medical diagnoses often require a second or third opinion.

How do you test inter observer reliability?
The other major way to estimate inter-rater reliability is appropriate when the measure is a continuous one. There, all you need to do is calculate the correlation between the ratings of the two observers. For instance, they might be rating the overall level of activity in a classroom on a 1-to-7 scale.

Why is it important to raise inter-rater reliability?
Evaluating inter-rater reliability is vital for understanding how likely a measurement system will misclassify an item. A measurement system is invalid when ratings do not have high inter-rater reliability because the judges frequently disagree.
How can you improve the reliability of an observation in psychology?
- Training observers in the observation techniques being used and making sure everyone agrees with them.
- Ensuring behavior categories have been operationalized. This means that they have been objectively defined.
How do you increase the validity of an observation?
Another way of improving the reliability of an observational study is to ensure that the categories are clearer. This refers to whether a study measures or examines what it claims to measure or examine. Observations are said to often lack validity for a number of reasons.
How can internal validity be improved in quantitative research?
- They occur in a lab setting to reduce variability from sources other than the treatment.
- Use random sampling to obtain a sample that represents the population.
- Use random assignment to create control and treatment groups that are equivalent at the beginning.
How can you improve the reliability of a questionnaire?
If people respond to the survey questions the second time in the same way they remember responding the first time, this will give an artificially good impression of reliability. Increasing the time between test and retest (to reduce the memory effects) introduces the prospect of genuine changes over time.
How can you improve validity and reliability in qualitative research?
Reliability in qualitative research refers to the stability of responses to multiple coders of data sets. It can be enhanced by detailed field notes by using recording devices and by transcribing the digital files. However, validity in qualitative research might have different terms than in quantitative research.
