100
This is a subgroup of the target population that the researcher plans to study for the purpose of making generalizations about the target population.
What is a sample?
100
individual scores from an instrument should be the same on repeated administration of the instrument and should be free from measurement error and consistent.
What is reliability?
100
the overall trends or tendencies in your data, validity, and relative standing
What is descriptive statistics?
100
infers from a sample to a population of participants
What is inferential statistics?
100
this is what all Counselors and Counseling Associations follow through guidelines and policies
What are ethics?
200
This is the difference between the sample estimate and the true population score is
What is sampling error?
200
This is a type of reliability has each participant in the study completes the instrument twice at different levels and only one version of the instrument
What is test-retest reliability?
200
these are the measures of central tendency
What are mean, mode, and median?
200
range of values that are consistent with the observed datea that is likely to contain the actual population mean is known as
What is confidence interval or interval estimate?
200
in 1971 this experiment was developed by Stanford Psychology Dept to find the effects of normal college students being prisoners and guards led to unethical practices
What was the Zambardo's Prison Experiment?
300
These are the 3 types of Probability sampling
What are simple random sampling, stratified sampling, and multistage cluster sampling.
300
means the scores from an instrument are reliable and accurate if they are consistent across the items on the instrument
What is internally consistent reliability?
300
this is the square root of the variance
What is standard deviation?
300
Identifying the null and alternative hypothesis, setting the level of significance or alpha level for rejecting the null hypothesis, collect data, and compute the sample statistic with probability (p value), and make a decision about rejecting or railing to reject the null hypothesis (Type I or type II error)
What are the 5 steps in Hypothesis testing?
300
statement that participants sign before they participate in a research study, rights of participants are protected.
What is an informed consent form?
400
These individuals are selected for a sample because they are available, convenient and represent some type of attribute or characteristic in a study
What is nonprobability sampling?
400
If the items are scored as continuous variables and this provides a coefficient to estimate consistency of scores on the instrument and used for internal consistency is known as
What is coefficient alpha?
400
distribution of scores by participants that is represented by a bell shaped curve
What is normal distribution or normal probability curve?
400
hypothesis testing procedure in which there are two separate groups of people tested and the population variance is unknown is called
What is the independent t test?
400
privacy of the participant and information provided, understands the rights of the individual participating in the study, what is said in or during will stay in the study and be anonymous.
What is confidentiality?
500
the researcher selects individuals from the population so that each person has an equal probability of being selected from the population
What is probability sampling?
500
a formula for calculating reliability of internal consistency of scores, relies on only half of the instrument being used
What is Kuder-Richardson split-half test?
500
This is the percent of the normal distribution between -1 and +1 standard deviation from the mean is
What is 68%
500
this determines the significance of a hypothesis that is being tested using difference or change scores from a single group of people is called
What is dependent t test?
500
providing false information or data is unethical practice in a study and is known as this to a participant
What is deception?
