Answer:Validity
Explanation:
Validity is measure of how valid the research is which means it gives solid relevant result which were initially intended. It is a test of how valid both your design and method of the research is.
There are various factors that can affect validity of the research.
There are internal factors that can affect validity of the research those are the ones that occur within the study such as failure to monitor vital variables of the study or using the inaccurate instrument to gather the needed data.
Below are the factors that has an impact on internal validity.
-size of the studied population
-instruments used
-history
-subject variability
-available time to gather data
- attrition
External validity are affected by the external factors such as the place where you conduct your research which may restrict the ability to obtain actual results . It can also be affected by the things like not being able to balance your subjects for example focusing on one gender and race eventhough your research is about all the types of people at large.
Crucial factors that affects external validity.
- The effect of time
- method use to collect data
- characteristics of the chosen population
- experiment effect
- interaction of subject selection
Answer:
culturally biased
Explanation:
culturally biased refers to an assumption that a certain phenomenon from our culture can be equally observed on the same level by other culture.
Let's take a look at this question:
<em>National Collegiate Athletic Association (NCAA) basketball championship start?"</em>
There are two problems with this question:
- To answer this, you need to be familiar with basketball culture.
- Even if you are familiar with basketball culture, someone from outside united states is most likely wouldn't be familiar with the term that is used by Americans.
Because of these reasons, using that question to measure intelligence indicates that Dr. Ambrosia might be having a cultural bias since dr Ambrose assume that everyone from other culture would just understand the term from Dr. ambrose's culture.
In the confidence interval method the sample data must come from a population that is normally distributed with no outliers.
A confidence interval is a range of values derived from observable data at a desired level of confidence that may include the parameter's true value. The confidence level, such as a 95% confidence level, refers to the accuracy of the estimating process rather than the degree of assurance that the computed confidence interval accurately represents the true value of the parameter under investigation. Confidence intervals are typically written as (some value) ± (a range). The range can be expressed as a percentage or as a real amount. The equation used to determine the confidence interval varies depending on which standard deviation is known.
