MEASURES OF CENTRAL TENDENCY
DGD
1 of 36
what are these?
averages that giv info about most typical values in set data
2 of 36
three to consider?
mean / median / mode
3 of 36
- mean
dfgdf
4 of 36
or the?
avg
5 of 36
why most sensitive?
requires all scores in calculation
6 of 36
which means its more representative of?
data as a whole
7 of 36
but easily distorted by?
extreme values
8 of 36
- median
dfdg
9 of 36
what is it?
middle value when arranged highest to lowest
10 of 36
is it affected by extreme scores?
no
11 of 36
why less sensitive than mean?
not all scores included in final calculation
12 of 36
- mode
ddgfd
13 of 36
what is it?
most frequently occuring score
14 of 36
in some sets there may be two modes?
bi-modal
15 of 36
or no mode if?
all scores different
16 of 36
is it representative of data a a whole?
no
17 of 36
for some data like what mode is only method u can use?
category data
18 of 36
MEASURES OF DISPERSION
DGDFG
19 of 36
based on what baout scores?
spread
20 of 36
and we focus on two of these being?
range / standard deviation
21 of 36
- range
dfgd
22 of 36
calculation of?
spread of scored
23 of 36
and worked out by?
taking lowest from highest and adding one
24 of 36
why do we add one?
allows for fact raw scores often rounded up / down when recorded
25 of 36
adding one accounts for?
margin of error
26 of 36
adv is that its easy to?
calculate
27 of 36
but only takes into account?
two most extreme values
28 of 36
and this may be?
unrepresentative of data set as whole
29 of 36
doesn't give fair representation of?
general spread of scores
30 of 36
- standard deviation
dfgdg
31 of 36
single value that tells what/
how far scores deviate from mean
32 of 36
the larget the standard deviation the?
greater the dispersion
33 of 36
w/ conditions of experiment large SD sugests?
not all pps affected same way
34 of 36
why is it more precise measure of dispersion?
includes all values w/in final calculation
35 of 36
but like the mean?
cna be distorted by single value
36 of 36
