Answer 1

Level of data can be categorised in 4 ways

Nominal data

Where data is used as just a label, cannot be used for any statistical analysis.

Ordinal data level of measurement

Where data value has a meaningful order. Like order of school education.

Interval data

Where data is in form of interval and we can get the significant difference between them

Ratio scale

Where data is in form of ratio where you can measure variable in another form of variable.

Now you will get your answer easily

1) temperature in Celsius

It has no meaning order so comes under NOMINAL DATA

2)level of education

It comes under ORDINAL DATA

Where graduate is higher than under graduate which is higher than high school....

3) name of respondent's favourite sports team

Comes under NOMINAL DATA because it has no meaning order, only a label for respondents.

4) blood alcohol concentration

It is percentage of alcohol in blood so it comes under RATIO DATA

5) kelly blue book vehicle condition

Comes under NOMINAL DATA

6) hair colour

Comes under NOMINAL DATA as it shows label for every person.

7) speed in mph comes under RATIO DATA where we can measure it in form of distance per hour/minutes of time.....

8) gender comes under NOMINAL DATA As it is label of that person.

9) level of satisfaction comes under INTERVAL DATA where your satisfaction comes under 0-10 10-20.... and so on

10) sales tax rate .. it is a rate so comes under RATIO DATA

Thanks....
