Introduction In the world around us, there are a lot of questions and situations that we want to understand, describe, explore and access. For example, • How many hospitals are there in different cities of Pakistan? • How many children were born during the last 10 years? • How many doctors will be required in the next 5 years? To know about such things, we collect information and present it in a manageable way so that useful conclusions can be drawn. The branch of statistics that deals with this process is called Information Handling.Consult PTB Math Book 10th(Science)
