PsyTeachR FQA Ch. 8

population

All members of a group that we wish to generalise our findings to. E.g. all students taking Psychology at the University of Glasgow. We draw our testing sample from the population.

ordinal

Discrete variables that have an inherent order, such as number of legs

integer

A data type representing whole numbers.

nominal

Categorical variables that don't have an inherent order, such as types of animal.

binomial distribution

The distribution of data where each observation can have one of two outcomes, like success/failure, yes/no or head/tails.

likert

A rating scale with a small number of discrete points in order

probability

A number between 0 and 1 where 0 indicates impossibility of the event and 1 indicates certainty

uniform distribution

A distribution where all numbers in the range have an equal probability of being sampled

continuous

Data that can take on any values between other existing values.

distribution

A way to describe the shape of data

interval

data which comes in the form of a numerical value where the difference between points is standardised and meaningful

discrete

Data that can only take certain values, such as integers.

inferential

Statistics that allow you to make predictions about or comparisons between data (e.g., t-value, F-value, rho)

Chi square

An inferential test used to compare observed frequencies with expected frequencies in categorical conditions

simulation

Generating data, as opposed to collecting data, from summary parameters such as the mean and standard deviation

ratio

data which comes in the form of a numerical value where the difference between points is standardised and meaningful but has a meaningful zero

sample

A subset of the population that you wish to make an inference about through your test.

normal distribution

A symmetric distribution of data where values near the centre are most probable.

The end!
