Measuring the Mind - supersession 2020

The group in an experiment that is exposed to manipulation of the independent variable

Temperature and a 12 hr Clock are examples of which kind of Scale of Measurement?

Descriptive statistic & measure of central tendency; exact halfway point of data distribution

Occurs when an extraneous variable makes it difficult to sort out the effects of the IV

A measure of variability which denotes the difference between the smallest and largest value in the dataset

The arithmetic average

Variable which has intermediate values between data values i.e. infinite decimals

Placing, 1st, 2nd or 3rd OR being allocated a Pass, Credit, Distinction, HD are examples of which Scale of Measurement

An instrument category used to measure aptitude and performance

The process of selecting participants who are members of the population you want to research

A link or association between variables that allows for prediction but does not infer causation

The spread or dispersion of data, including the extent to which scores vary from the mean

A measure of variability in data

Another variable we know may affect the dependent variable and is therefore controlled for

Research performed over time with the same participants

Variable which has no intermediate values between data values and they are nominal/oridnal

Statistics helpful in organising and summarising (but not interpreting) data

Any variables other than the IV that might influence the DV in an experiment and creates "noise"

The main kind of sampling used in qualitative research

Use of in-depth methods incl. conversations, interviews to understand the how and why of human behaviour

Measure of variability that is the difference between the highest and lowest scores in the data set

Occurs when a researcher's expectations influence the results of a study

The variable that an experimenter manipulates in order to observe its impact

Height, Weight, Reaction Time and Exam Score are all examples of which kind of Scale of Measurement?

A periodical that publishes technical and scholarly material within a discipline

Judgment inferred from statistics that probability of observed findings occurs by chance is very low

Statistics used to interpret data in an experiment and draw conclusions

The degree to which test results or evidence occurs repeatedly

The score that occurs most frequently

A statistic that indicates the degree and direction of relationship or association between variables but not cause

An instrument category that includes surveys or inventories

Procedures for systematically watching behaviour to summarise if for scientific analysis

The degree to which results occur repeatedly

The square root of the mean squared deviation of each data point from the mean

The group in an experiment that is not exposed to manipulation of the independent variable

A process for selecting participants whose characteristics reflect the characteristics of the population they were drawn

Precisely defines ea. variable in study in terms of operations needed to produce/measure them

A larger group from which a sample is drawn and to which the researcher wishes to generalise

The variable that changes in response to another variable

The degree to which the test measures what it is supposed to measure

Distribution of subjects in experiment where each has equal chance of being assigned to any group

Sex, Gender, Race, Nationality, Colours are examples of which kind of Scale of Measurment

The process of selecting a group of participants from a population without equal chance of being selected

The measure of variability that is the mean squared deviation of each data point from the mean

Research method in which IVs are manipulated and which permits causal interpretation

A tentative statement about the expected relationship between two or three variables
