Yeah Oh Table one below shows the recorder data from

00:10

each scavenging event in this study that whale species in

00:14

size and wind direction and speed and figure one illustrates

00:20

that relationship of wind speed Teo Maximum shark's eyes straight

00:24

line and figure one is a linear regression fit to

00:27

the data points to illustrate a direct relationship between wind

00:30

speed and maximum shark sides All right next up based

00:35

on the information and figure one Which of the following

00:38

best describes the linear regression applied to the data for

00:41

maximum shark's eyes versus the wind speed We're going struck

00:47

size one side of the equation here in wind speed

00:50

on the other list of Graff So the question originally

00:53

made us want to run for cover from Sharknado or

00:57

Meg NATO the Mega Ladan storm that's coming soon you

01:00

know Then we realized the sharks weren't being picked up

01:03

and thrown around by that wind instead Well heavier winds

01:07

are probably carrying the oh so aromatic scent of dead

01:09

whale farther across the ocean and thereby drawing more sharks

01:13

to feeding event And many people don't realize this but

01:17

there's a new Chanel number six coming out called Dead

01:20

Whale Yeah well you see the commercial well As wind

01:23

speed increases so does the maximum shark's eyes So this

01:27

is a positive correlation or positive relationship Now eliminate all

01:31

answer choices that are negative like Kimber today and see

01:34

their goodbye in a negative relationship There's just no communication

01:38

People just go their own separate await a different kind

01:41

of thing Yeah mathematically That means maximum shark's eyes would

01:45

decrease as the wind speed increased Write thie r squared

01:49

value known as the coefficient of determination It would be

01:53

shown on the graph as point five three as in

01:56

B Well thiss value help Scientists understand how well that

01:59

data fits their predictions that the data is directly related

02:03

The point will fit the line nearly perfectly Like you'd

02:06

say That's an r squared correlation of one The higher

02:10

the number as being positive means everything is kind of

02:13

map through the same line If the relationships more complex

02:16

on his obvious Nona's directly well correlated and a linear

02:20

regression line tends to not run through a large fraction

02:24

The point like they're all scattered around it like an

02:26

ugly cloud Yeah well the more points a trend line

02:29

runs through the higher the r squared number the more

02:32

predictable it is And basically what this chart is telling

02:35

us is that as wind speed increases more dead whale

02:39

sentence and way out into the ocean tracts bigger and

02:42

bigger sharks to that dead well so that's it The 00:02:45.69 --> [endTime] answer is B positive correlation point five three
