    Maps can represent a variety of information from how fast the wind blows in different parts of the country to which roads to take to get to your favorite ice cream parlor. Maps are very useful in that they help people see things within the real world on a smaller scale. Scale is important in that it shows the map reader exactly how far, wide, tall or long an object or distance on the map is. For example, if a map shows the distance between 2 towns to be 2 inches, and the scale represents an inch being 100 miles, then the distance between the 2 towns is 200 miles. This can hold true for buildings and monuments as well, If the scale tells the reader that 1 inch is equal to 100 feet and a building measures 3 inches tall, it is 300 feet tall.

Classify and know the difference between various types of data

Data is just another word for information.

There are a few different types of data. For example, there’s data we can represent with numbers, and data we can’t represent with numbers.

Qualitative – Cannot represent with numbers (something like eye colour, address or food preference)

Quantitative – Can represent with numbers (things like height, number of sisters or shoe size)

You can remember which is which because quantitative is the one with the N in it, for number.

There are now two types of quantitative data, discrete quantitative and continuous quantitative.

Discrete Quantitative – Data you count in chunks, 1, 2, 3… (things like number of sisters, shoe size, money)

Continuous Quantitative – Data you can’t count in chunks (things like height, time, distance)
