Q

Institutional Review Board (IRB)

A

An administrative body that provides review, oversight, guidance, and approval for research projects carried out by employees serving as researchers, regardless of the location of the research (such as a university or private research agency); responsible for protecting the rights and welfare of the human subjects involved in the research. IRB oversight is mandatory for federally funded research projects

26
Q

Interval variables

A

Variables that have equal units with an arbitrary zero point

27
Q

Line graph

A

A graphic technique used to illustrate the relationship between continuous measurements; consists of a line drawn to connect a series of points on an arithmetic scale; often used to display time trends

28
Q

Mean

A

A measure of central tendency that is determined by calculating the arithmetic average of the observations in a frequency distribution

29
Q

Measures of central tendency

A

The typical or average numbers that are descriptive of the entire collection of data for a specific population

30
Q

Measures of variability

A

Examination of the spread of different values around the measures of central tendency; these include the range, variance, and standard deviation.

31
Q

Median

A

A measure of central tendency that shows the midpoint of a frequency distribution when the observations have been arranged in order from lowest to highest

32
Q

Mixed-methodology

A

Research study approach that includes using both quantitative and qualitative data

33
Q

Mode

A

A measure of central tendency that consists of the most frequent observation in a frequency distribution

34
Q

Nominal variables

A

Variables in which a number is assigned to a specific category; such as a 1= male and 2 = female

35
Q

Normal distribution

A

A theoretical family of continuous frequency distributions characterized by a symmetric bell-shaped curve, with an equal mean, median, and mode; any standard deviation; and with half of the observations above the mean and half below it

36
Q

Ordinal variables

A

Ranked variables in which a number is assigned to rank a category in an ordered series but does not indicate the magnitude of the difference between any two data points

37
Q

Pareto chart

A

A bar graph that includes bars arranged in order of descending size to show decisions on the prioritization of issues, problems, or solutions

38
Q

Percentile

A

A measure used in descriptive statistics that shows the value below which a given percentage of scores in a given group of scores fall

39
Q

Pie chart

A

A graphic technique in which the proportions of a category are displayed as portions of a circle (like pieces of a pie); used to show the relationship of individual parts to the whole

40
Q

Presentation software

A

Software used to build slides when presenting a specific topic, idea, research data or any type of information

41
Q

Proportion

A

The relation of one part to another or to the whole with respect to magnitude, quantity, or degree

42
Q

Prospective study

A

A study designed to observe outcomes or events that occur after the identification of a group of subjects to be studied

43
Q

Qualitative research

A

Research design that collects types of data that includes a participant’s perceptions, attitudes, feelings or attitudes about a certain subject; methods used to collect qualitative data can include observations, focus groups, case studies, informal conversational interviews, and in-depth interviews

44
Q

Qualitative variables

A

Categorical variables; all are discrete and include both nominal and ordinal variables

45
Q

Quantitative study

A

Data collected for research studies that are collated numerically with descriptive, inferential, or predictive statistics

46
Q

Quantitative variables

A

Numerical variables; can be broken down into interval and ratio variables

47
Q

Quasi-experimental study

A

Similar to the experimental study except that randomization of participants is not included in a quasi-experimental study, the independent variable may not be manipulated by the researcher, and there may be no control or comparison group; these studies can be performed over time and may not include individual participants but whole healthcare systems

48
Q

Randomization

A

The assignment of subjects to experimental or control groups based on chance

49
Q

Range

A

A measure of variability between the smallest and largest observations in a frequency distribution

50
Q

The most common quantitative variables used in healthcare; these variables include numbers that can be compared meaningfully with one another; zero is truly zero on the ratio scale

51
Q

Research methodologies

A

Research studies that can range from exploratory or descriptive studies that strive to generate new hypotheses based on data collected to experimental studies that provide interventions or treatments that can reduce the spread of an existing disease

52
Q

Retrospective study

A

A type of research conducted by reviewing records from the past (for example, birth and death certificates or health records) or by obtaining information about past events through surveys or interviews

53
Q

Scatter charts

A

A graph that visually displays the linear relationships among factors

54
Q

Standard deviation

A

A measure of variability that describes the deviation from the mean of a frequency distribution in the original units of measurement; the square root of the variance

55
Q

Stem and leaf plots

A

A visual display that organizes data to show its shape and distribution, using two columns with the stem in the left-hand column and all leaves associated with that stem in the right-hand column; the “leaf” is the ones digit of the number, and the other digits form the “stem”

56
Q

Statistical packages

A

Software that can be used to facilitate the data collection and analysis process; these packages simplify the statistical analysis of data and are often used in addition to spreadsheet software

57
Q

Table

A

An organized arrangement of data, usually in columns and rows

58
Q

Variability

A

The dispersion of a set of measures around the population mean

59
Q

Variance

A

A disagreement between two parts; the square of the standard deviation; a measure of variability that gives the average of the squared deviations from the mean; in financial management, the difference between the budgeted amount and the actual amount of a line item; in project management, the difference between the original project plan and current estimates

60
Q
