In this lesson, we will learn about the data handling cycle, and will classify data into different categories.

In this lesson, we will learn how to write a suitable hypothesis, and the difference between primary and secondary data sources.

In this lesson, we will discuss the difference between a sample and a census, and how to avoid bias in sampling.

In this lesson, we will discuss how to ask appropriate survey questions, and how to give appropriate answer options to those questions.

In this lesson, we will learn how to find the mean from a set of data.

In this lesson, we will solve different types of problems requiring us to calculate the mean, and problems where we need to determine numbers that have a provided mean value.

In this lesson, we will learn how to find the mode, median and range from a set of data.

In this lesson, we will interpret differences between the mean, median, mode and range.

In this lesson, we will learn how to sort data into a frequency table.

In this lesson, we will learn how to find the mean from a frequency table.

In this lesson, we will learn how to find the median from a frequency table.

In this lesson, we will interpret bar charts, including finding the mean from a bar chart.
