______ step has been described as the “core” of qualitative analysis.
What is coding?
The most frequently occurring number in a data set.
What is the mode?
An approach that has a high amount of researcher control and requires random assignment.
What is a true experiment?
A symmetrical distribution in which 68% of data are within 2 standard deviations.
Naturalistic, inductive, and focus on meaning
What are characteristics of qualitative research?
The average of all of the identified numbers in a data set.
What is the mean?
An approach that has a moderate to high amount of research control, with an intervention, but does not have random assignments of groups.
What is quasi-experimental?
"We hypothesize that there will be a significant difference between group means"
What is a nondirectional research hypothesis?
This research approach is not always qualitative, but is most commonly qualitative.
What is a case study approach?
The midpoint of the numbers in a data set.
What is the median?
A type of study that focuses on clarifying the extent of correlation between two variables.
What is correlational?
"We hypothesize that there will be a significant difference between group means, such that Group 1 means will be significantly lower than Group 2 means"
What is a directional research hypothesis?
A common approach to ethnographic research is as a ___________.
What is a participant observer?
Statistics based based on probabilities of the data being representative of the population.
What is inferential?
Descriptive research that concerns attempting to identify the effects of an independent variable after the fact. The independent variable is not under the control of the researcher but is of interest. The researcher therefore compares two or more groups who have had different experiences.
What is causal-comparative?
"We hypothesize that there will not be a significant difference between group means"
What is a null hypothesis?
Interviews, focus groups, natural observations, and transcripts
What are traditional methods of data collection in qualitative research methods?
The closer a correlation statisitc (r) is to 1, this suggests that a relationship between two variables is relatively _______.
What is strong?
Involves a condition that a control group has not experienced and there is no random assignment to groups.
What is static group comparison?
A ______ is an analysis technique that compares two means for one group based on a pretest and posttest data.
What is an independent t-test?
