In this problem we want to determine the scale of measurement for each of the following using these four types the first two is for categories nominal has no order but ordinal can use order for the categories the ratio variable is for the measurements that can describe by ratio for example a weight of 50 kilograms is twice the weight of 25 kilograms and 0 kilograms means there is no weight but the interval can describe a discrete variable that takes all numbers or another variable that can't be described as a ratio for example the temperature of 30 degrees celsius is not twice 15 and 0 slius does not mean there is no heat.
01:19
Then let's answer the questions.
01:23
First, the distance between cities.
01:27
Distance between cities falls in the ratio because we can describe it as twice the distance between another two cities.
01:37
Then its ratio.
01:41
The second one, ranking sizes of dresses by small, medium, large, this is category then we can use ordinary because it has an order from small to large 3 the types of bencessions use this is a categorical variable but it has no order then it's nominal 4 we have daily numbers of books sold by a bookshop however the number of sense is discrete but its ratio because it has a meaning of 0 this is the difference between the ratio and the interval.
02:34
The ratio has a meaning of zero.
02:37
The interval does not have a meaning of zero.
02:43
Zero slithes does not mean no heat, but zero kilograms means there is no object and it's weightless.
02:54
For 5.
02:56
The daily temperature in ajman, you've said that the temperature is interval.
03:06
Exam scores generally exam scores is considered ratio because it has a meaning of zero...
