# Data and Statistics

## Introduction to Data and Statistics

### Comparing Apples and Oranges

Mathematics is the language of science, and data is one of the founding pillars of science. So, of course maths would have the means to handle data and convert it into meaningful and comparable outputs.

## The Big Idea: What is Data?

Anything that can be grouped based on certain comparable parameters can be thought of as **Data**.

Taking a simple example;

One often hears the phrase, “**You can’t compare apples and oranges!**” What if we were to tell you, that you can, and in mathematics, you will end up comparing such seemingly unrelated objects quite often!

Let’s add the magical term that allows us to compare such disparate entities, context or as it’s often called officially, **parameters**. What are parameters? Well, they define the context in which the comparisons made are to lie and are to be quantified. For example, you can compare the number of seeds in an apple and an orange and that would constitute a **data set**. A data set is what allows us to compare and contrast the information given regarding a particular group and come up with meaningful interpretations and conclusions. This is a very basic example of a data set

Here are a few links that will take you through the journey that every Cuemath students undertakes in the pursuit of understanding Data and Statistics along with practice worksheets:

## How do You Teach Data Handling?

**Keep it simple:** When starting out, make sure your child is comfortable with pictographs and identifying how to create data sets. Working with pictographs is a very good way to internalize data sets from a very early age and build comfort with the topic of data handling.

**Chunking:** This is a universal preparatory technique. It centers around strengthening and staying in touch with concepts and topics that lead up to data handling. While data handling and statistics stands as a separate pillar of mathematics, it depends on you being very well versed with your grasp of basic operations. So, drill your additions, subtractions, multiplications and divisions between data and statistics problems.

**Flash Cards:** Flash cards are an excellent exercise tool. They help keep the most common concepts of a topic on the tip of your tongue. Make sure your child includes a daily 30-minute training session practicing with slash cards. This is what a flash card looks like:
