Qualitative Approaches
Identifying and holding back any preconceived beliefs or opinions about a phenomenon.
Bracketing
Visual representation of a study is achieved through scatter plots describes...
What is Correlation Design
Sampling design that involve random selection of elements from the population & yield more representative samples.
What is Probability Sampling
Which measure of central tendency is most affected by skewed data sets...
What is the Mean
When a relationship on one measured variable has high values and on another measured variable has low values. That relationship is said to be...
What is Negative or Inverse
If the p value is reported to be...(p>.05) what will the researcher report.
There is not enough evidence to reject the null hypothesis.
Typically used in grounded theory by analyzing data in an ongoing fashion and refining relevant catagories
Constant Comparison
The significance criterion - the risk the researcher is willing to accept of making a Type - I error (false positive)
Alpha
When the researcher's hand selects the participants the sample is said to be...
What is Purposive sampling
95% of the population will be within how many Standard Deviations from the mean.
What is Two
A variable that is extraneous to the independent and dependent variable. It can be controlled through statistical procedures
What is a confounding variable
Based on data from a sample a researcher can predict what may happen with at population based on laws of probability; this describes...
What is inferential statistics
Interpretive phenomenology, that focuses on the lived experiences of humans and how they interpret those experiences
Hermeneutics
Testing 3 or more groups by comparing variability between groups to variability within groups.
Analysis of variance (ANOVA)
When a researcher sets up an experimental design of pre-test and post-test between two or more groups and the groups are non-equivalent.
What is a Quasi-Experimental research
A range measurement that looks at the middle 50% of participants in a sample is...
What is the Interquartile range or IQR
In statistical testing, the probability that the obtained results are due to chance alone.
What is the p value
Indicating the precision of individual scores. The standard deviation divided by the square root of the sample size.
What is the Standard Error of the Mean (SEM)
The effect on the dependent variable resulting from subjects' awareness that they are participants under study.
What is the Hawthorne Effect
Tests differences in proportions
What is Chi Square
In-depth interviews until saturation occurs; expert review by qualified researchers; Observations by trained research assistants; all create credibility for qualitative studies and is known as...
What is Triangulation
When two samples with identical means differ in variability.
What is Kurtosis
The null hypothesis and the alternative hypothesis can not exist at the same time. There is a significant difference & there is no difference. This is said to be...
What is a Mutually Exclusive Event
When you accept the null when it is False =
How do you fix this problem
Type II Error
Increase the sample size
A critique of society, with the goal of effecting social change.
Critical Theory
Summarizes the strength of the effect of the independent variable on the dependent variable
What is Cohen's d
Data measurement that has negative and positive numbers are known as what...
What is Interval Level data
The range of values within which a population parameter is estimated to lie, at a specific probability
What is The Confidence Interval
Parametric in nature. Comparing two group differences on an outcome variable.
What is a t-test
Rejecting the null when it is true =
How can you fix this problem
Type I error
Reduce the alpha from .05 to .01
