Largest Hydroelectric Plants. According to Wikipedia, the world's five largest hydroelectric plants, based on installed capacity, are as shown in the following table. Capacities are in megawatts.

a. What type of data is given in the first column of the table?

b. What type of data is given in the fourth column?

c. What type of data is given in the third column?

The data is given as:

we have to find out the type of data in the first column of the table.

Individuals are placed into categories by categorical or qualitative criteria, whereas quantitative variables are numerical variables.

Because the rank has numerical values, it is a quantitative variable. Because the rank can only take positive integer values, it is likewise a discrete variable.

The data is given as:

we have to find out the type of data in the fourth column of the table.

Individuals are placed into categories by categorical or qualitative criteria, whereas quantitative variables are numerical variables. Because capacity takes on numerical values, it is a quantitative variable. Because the rank can take decimal values, the capacity is also a continuous variable.

The data is given as:

we have to find out the type of data in the third column of the table.

Individuals are placed into categories by categorical or qualitative criteria, whereas quantitative variables are numerical variables. Because a country is not a numerical variable, it is a qualitative variable. China, Brazil, and Canada are all possibilities.
