+8262 1) Complete the explanation of how can you use and compare data to solve real-world problems.
For numerical real-world data, you can graph the data and identify similarities and differences in corresponding parts of the graph. For categorical real-world data, you can graph the data and compare the centers, spreads, and shapes of the graphs.
Is this correct?

Is this correct? No it is not right.
Say you were going to study something about the cars in the carpark.
1) Examples of numerical staudes that could be done is
Size of engine, length, width, Year of manufacture, how many people arrived in it, age of drive, etc etc See all thise things will be collections of numbers.
2) Examples of categorical data could be. Colour of the car, Make of the car, the ethnicity of the driver. See, none of these are numbers! [They are all categories] So you cannot really compare central tendancies or spread of the data. I suppose you can say that 70% of the cards are white or red. But you can't say t hat the average car is red. This does not make sense.
