Discrete versus continuous has to do with if the number of values is countable or uncountable.
00:06
It's best to visualize this on a number line.
00:10
Countable data is one where we can actually figure out how many data points there are.
00:15
It's things that stop and start on a number line.
00:18
So, for example, if my data points fall at 1, 2, 3, and 4, so let's say one data point for each, i can physically count the number of dots.
00:28
There's one here, one here, one here, and one here.
00:31
There's not an infinite amount of numbers in between.
00:34
So this is discrete.
00:35
The data points themselves are countable.
00:39
Continuous, however, can continue on forever.
00:41
There's an infinite number of numbers that are in between each thing.
00:44
So if i started at one and then filled in a line all the way to four, i actually can't count the number of data points in there because i could count 1 .1, 1 .2, 1 .3, but i could also count the numbers in between those, 1 .05, 1 .04.
01:05
There's always more number data points inside this.
01:08
So continuous goes on forever.
01:09
It's not broken up, whereas discrete, it's single discrete data points...
