Definitions
What type of observation occurs without the participants' knowledge?
overt
this type of question allows only a limited number of responses
close-ended question
weight of an ice cream scoop
ratio variable
the researchers determine that there is a significant difference in final exam grades between students that prefer to study outdoors vs indoors, when in reality there is no difference.
type 1 error
The population to which you want to infer your results
target population
Measurements of the human body
anthropometric measurements
in qualitative research, this occurs when there is no new information being gathered from additional data collection (you can stop data collection at this time)
data saturation
temperature of ice cream
interval variable
the researchers determine that there is no significant difference between in final grades between students that spend at least 4 hours studying and students that spend less than 4 hours studying, when in reality there is a difference
type 2 error
the population that is invited to participate in your study
sample population
the process of removing potentially identifying information from a data file so that the data can be shared with others
deidentification
a structured consensus-building method in which experts discuss different perspectives
delphi method
asking participants their favorite ice cream flavor
nominal/categorical variable
the smaller the p-value, the greater the likely-hood of a __________ error
type 2
The population that participates in your research
study population
a systemic check of financial records and other actions and decisions that is conducted to confirm accuracy and compliance with standards of practice
audit
a guide written for a particular study that describes each variable and specifies how the collected information will be entered into a computer file
codebook
Asking participants to fill out a likert scale questionnaire on different ice cream flavors (I strongly agree ==> I strongly disagree)
ordinal/ranked variables
the probability of a type 1 error is designated by which Greek letter?
alpha
the population from which individuals will be drawn to ask to participate
source population
this type of analysis uses rate ratios, odds ratios, and other comparative statistics to compare TWO variables
bivariate analysis
this type of sampling chooses participations that are easy to access to the researcher
convenience sampling
asking participants if they have eaten ice cream before (yes or no answer)
nominal/categorical variable (also a dichotomous variable)
the probability of a type 2 error is designated by which Greek letter
Beta
the population represented by n
study population
