By the 6th grade, you're starting to become a sophisticated mathemagician. You'll be able to add, subtract, multiply, and divide any non-negative numbers (including decimals and fractions) that any grumpy ogre throws at you. Mind-blowing ideas like exponents (you saw these briefly in the 5th grade), ratios, percents, negative numbers, and variable expressions will start being in your comfort zone. Most importantly, the algebraic side of mathematics is a whole new kind of fun! And if that is not enough, we are going to continue with our understanding of ideas like the coordinate plane (from 5th grade) and area while beginning to derive meaning from data!

Data and statistics
In statistics, we try to make sense of the world by collecting, organizing, analyzing, and presenting large amounts of data. For example, you may survey your friends about what tv show is most popular, but the small sample size will not give you an accurate idea of what ALL 6th graders like to watch. To do this you must survey a cross section of students from all around the country and all backgrounds. The data can then be statistically analyzed to give a more accurate picture of what tv show is most popular. So let's dive into a discussion of statistics, including box and whisker plots, bar charts, pictographs, line graphs, and dot plots.

### Dot plots and frequency tables

A dot plot is like a bar chart, but it displays data using dots (not bars). And a frequency table is like a dot plot, but it displays data in a simple table (not a fancy diagram).

### Statistical questions

Statistics help us answer many questions, but not all questions are statistical. In this tutorial, we'll learn to tell the difference between a statistical question and a non-statistical question.

### Creating histograms

Histograms are similar to dot plots and bar graphs, but they work a little bit differently. In this tutorial, we'll learn how histograms work and when to use them.

### Mean and median

Mean and median are measures of "central tendency." That is, they help us find the center (or middle) of the data. In this tutorial, we'll learn how to compute mean and median.

### Box plots

Whether you're looking at scientific data or stock price charts, box-and-whisker plots can illuminate patterns in your life. This tutorial covers what they are, how to read them, and how to construct them.
