00:01 Hello students, as per the given question, we need to check if the people are randomly selected or a student by their school security numbers.

00:15 So the level of measurement in this case is nominal.

00:26 So the social security numbers are used as identifiers and do not have any inherited order or numerical significance.

00:35 So we see that it is a nominal scale.

00:37 And coming to the next bit where a statistic statistician records the years in which the super bowl is won by the team that won the coin toss.

00:51 So for this we say that the level of measurement here is ordinal.

01:02 That is because the year represents an order sequence, but the difference between the year and the year do not have consistent or a meaningful interval.

01:12 So it's about the order in which the event occurred.

01:16 So we say that it is an ordinal scale in general.

01:20 And coming to the next part where the exact times that a randomly selected students spent on their phone last week were recorded.

01:29 So is this is an example of discrete or continuous data we need to define.

01:34 So we say that this data is continuous and continuous data that is because the continuous data can take on any values within a given range.

01:47 And in this case the time spent on phones can be measured with high precision including fraction of seconds...
