Question

the standard deviation is a measure of spread... so if every score is increased by the same value, then the gaps between the data don't change...

and in the other question, again standard deviation is a measure of spread

the smaller the standard deviation, the closer the data is...

the larger the standard deviation the more spread the data...

Answer 1

Ok someone has already explanied this to me mostly, but now I need to see if I can get the correct answers

Answer 2

1. C.

Answer 3

2. not sure

Answer 4

ok dude I did what you said and I got C .. now maybe I didnt use 8 though

Answer 5

1st choice is correct...

Answer 6

in the graphs... the mean is the centre of the normal curve. Do the 2 curves have the same centre?

Answer 7

yes they do

Answer 8

your 1st choice.... that is C

Answer 9

ok so 2. would be D

Answer 10

nope... standard deviation is a measure of spread... if the standard deviations where the same there your be 1 curve

so the larger the standard deviation the more spread the data.

Answer 11

oh sorry the deviation wouldnt be the same as the taller one

Answer 12

in fact its ACTUALLY C

Answer 13

1. C 2. C

Answer 14

the measures of spread... and marked on the horizontal axis... so the larger the standard deviation the wider the horizontal spread

Answer 15

yes so C

Answer 16

the first one is way taller then the second one

Answer 17

so we agree the means are the same...

which is narrower that one has the smaller standard deviation

Answer 18

oh I see so both are bigger not just the deviation

Answer 19

is that what you mean

Answer 20

its answer A... means are the same and population 1 has the smaller standard deviation because its a narrower curve

Answer 21

so if its narrower its smaller

Answer 22

narrower means smaller standard deviation
