Discrete data or variable and continuous data or variable.
00:06
Discrete, the key thing here, discrete data is called countable.
00:14
You can count the items like number of coins in a bag, number of dice you are throwing, number of children in a family.
00:23
Discrete data is countable.
00:26
Continuous is measurable.
00:30
You measure something like weight.
00:32
With a weighing machine you measure height you measure volume you can't count continuous data you measure it and round it the nearest by the whole number or 1dp 2dp and so on so here then what we have in item a is miles per gallon of a car or that is continuous because what we are doing here is measuring distance miles traveled per gallon.
01:09
The gallon is a volume.
01:10
You measure.
01:11
So overall that's continuous.
01:16
Part b, maximum speed of wind.
01:19
Well, you measure speed, you can't count speed.
01:24
So again, b is also continuous.
01:28
It's 45 .392 miles per hour.
01:34
C.
01:35
Distance thrown.
01:36
Again, you measure how far you throw a baseball.
01:39
So you measure...
