12
Q

T or F: Participant reactivity typically remains a large obstacle throughout the entire course of observation and does not diminish overtime.

A

False. Typically diminishes as those under observation tend to forget someone is watching.

Q

To be considered ethically sound, what must a reacher prove to conduct concealed observations?

A

They must demonstrate that concealment is necessary and be reasonably sure that participants would consent if given the option

Q

What are coding systems in observational research?

17
Q

What is a frequency/count recording?

A

Documenting each time a target behaviour occurs

18
Q

The way in which the observer notes the particulars of the behaviour or phenomenon they are observing is referred to as what?

A

An observation schedule

19
Q

T or F: The observation schedule as well as coding definitions and categories are typically refined when observers are trained.

A

True

20
Q

T or F: A researcher’s investment in their study may compromise the ability to be objective when making observations.

A

True

21
Q

T or F: Observer training does not help minimize potential biases.

A

False

22
Q

What are blind observations?

A

An observational data collection technique in which observers are trained to look and code for particular behaviours but are uninformed about the overall purpose or hypothesis of the investigation

23
Q

What is the difference between intra-observer reliability and inter-observer reliability?

A
  • Intra-observer: The extent to which an observer is consistent within their own codings
  • Inter-observer: The level of agreement between different observers’ coding of the same situation
24
Q

What is pilot testing?

A

A trial run to test and refine a study prior to carrying out the actual research

25
Q

What is interval recording?

A

Breaking down an observational period into equal, smaller time period, then documenting whether a target behaviour occurred during each time period

26
Q

What is continuous recording?

A

Documenting all behaviours of a target individual during a specified observation period

27
Q

What is contrived observation?

A

When the researcher artificially introduces a variable of interest, then unobtrusively records what happens

28
Q

What are descriptive statistics?

A

Statistics that describe or summarize quantitative data in meaningful ways

29
Q

T or F: Descriptive statistics allow for conclusions to be drawn about hypotheses.

A

False. That is what inferential statistics are for.

30
Q

What is the difference between a categorical and continuous variable?

A
  • Categorical: Can be classified into two or more distinct groupings
  • Continuous: Have an infinite number of different values between two given points
31
Q

What is a frequency distribution?

A

A summary of how often the individual values or ranges of values for each variable occurs

32
Q

What is the mode of a data set?

A

The most frequently occurring value

33
Q

Which measure of central tendency is used most often with categorical data?

A

Mode

34
Q

How is mode typically denoted?

A

M subscript O

35
Q

What is the mean of a data set?

A

The mathematically calculated average

36
Q

How is mean typically denoted?

A

M

37
Q

What is the median of a data set?

A

The value found at the exact middle of the set of scores

38
Q

How is median typically denoted?

A

Mdn

39
Q

What is Cohen’s kappa coefficient?

A

A statistical measure of inter-observer reliability between two observers for categorical items

40
Q

Why is Cohen’s kappa coefficient a better measure of agreement than determining the percentage of overlap between observers?

A

Because it takes into account the agreement occurring by chance
