3 Exam Q&A 100% Solved
MEASURE OF CENTRAL TENDENCY - ✔✔Mean, median, and mode.
They are used to organise and summarise a set of data.
= numerical values that best reflect the centre of a distribution of scores
@tells us about how high/low on average a group or individual scored in a
measure
MEAN - ✔✔the arithmetic average of a distribution - average of the
expectation of data
= obtained by adding the scores and then dividing by the number of scores
#tells us about data as a whole and not about individual data points
#Good at measuring things that are nomrally distributed
NORMAL - ✔✔=a distribution of data that has roughly the same amount of
data on either side of the middle
=most common values around the middle of the data
, DISTRIBUTION - ✔✔-the arrangement of data
=shows how often each value occurs in a data set
FREQUENCY - ✔✔=how often each value occurs in the data set
NORMAL DISTRIBUTION - ✔✔=describes a symmetrical bell shaped
curve that shows the distribution of many physical and psychological
attributes
MEDIAN - ✔✔=the middle score in a distribution
=half the scores are above it and half are below it
=middle number if we line up our data from smallest to largest
MODE - ✔✔=the most frequently occurring score(s) / value in a distribution
#most popular value
BIMODAL DATA - ✔✔=a histogram will have two peaks as the data has
two modes = like a camel's back
= example of MULTIMODAL DATA
*has many values that are similarly common
#usually results from 2 or more underlying groups all being measured
together
NORMALLY DISTRIBUTED - ✔✔= represents the distribution of variables
as a symmetrical bell-shaped graph.
