By in Uncategorized with 0 Comments

Bar scales show scale using a graphic format. This type uses a set of numbers that represents the object or a landmark. Ratio scale allows any researcher to compare the intervals or differences. This scale is used to calculate all the scientific variables. There are three main ways that scale is indicated on a map: graphic (or bar), verbal, and representative fraction (RF). The first way is the ratio of the size of the generating globe to the size of the Earth. Nominal variables are used to “name,” or label a series of values. Examples are: 'one centimetre to one hundred metres' or 1:10,000 or 1/10,000 'one inch to one mile' or 1:63,360 or 1/63,360 'one centimetre to one thousand kilometres' or 1:100,000,000 or 1/100,000,000. The scale of a map is \(1:50,000\). The distance is measured as \({3}~{cm}\) on the map. In this example we can see that 1 unit on the map represents 25 000 000 units in real life. The scale of a map is the ratio of a distance on the map to the corresponding distance on the ground.

Map scales can usually be found on the outer edge of a map, usually near the … Stated • 1 cm = 250 km Scale Linear Scale Ratio • 1:25 000 000 Scale 6. The most popular examples of ratio variables are height and weight. It is calculated by assuming that the variables have an option for zero, the difference between the two variables is the same and there is a specific order between the options. Ratios are usually written in the form a:b and can be used on maps to show the scale in relation to real life. Ratio scale doesn’t have a negative number, unlike interval scale because of the absolute zero or zero point characteristic. The map scale of the world is 1:50,000,000 and a map of a country usually scales from 1:600,000 – 1:2,000,000. Here the unit for time can be kept constant and a unit for distance traveled can vary, for example, can be in kilometers or miles which means 20 km/hour is equivalent to 12.43 mph. Interval scales give us the order of values and also about the ability to quantify the difference between each one.
