# Year Seven Mathematics Worksheets

As kids start to learn math, they’ll come across various concepts that help them understand how to make educated guesses about things they don’t know. This is called making inferences, and it’s an important skill to have in life, both in and out of the classroom. One of the key areas where kids will learn to make inferences is in statistics, where they’ll look at a sample of data from a larger population to make guesses about the entire group.

For example, let’s say a school wants to know the average height of its students. They can’t measure the height of every student in the school, so instead, they measure the height of a smaller group of students, called a sample. Based on this sample, they can then make inferences about the entire population of students in the school.

To make inferences about a population with an unknown characteristic, kids will learn to use measures of central tendency, like the mean, median, and mode. These measures give them a general idea of what the entire population might look like. For example, the mean is the average of all the numbers in a sample, and it gives a good idea of what the average height of the students might be. The median is the middle value in a set of numbers, and it gives a good idea of what the most typical height might be. The mode is the number that appears most often in a sample, and it gives a good idea of what the most common height might be.

In addition to measures of central tendency, kids will also learn about measures of variability, like range and standard deviation. These measures give a sense of how much the data in a sample varies. For example, the range is the difference between the largest and smallest numbers in a sample, and it gives a good idea of how much the height of students varies. The standard deviation is a more complex measure that gives a sense of how far away each number in the sample is from the mean, and it gives a good idea of how much the height of students varies from the average.

Overall, learning to make inferences about a population with an unknown characteristic is an important part of understanding statistics and math. By using measures of central tendency and variability, kids can gain a better understanding of what a larger group of things might look like based on a smaller sample. With practice, they’ll be able to make educated guesses about things they don’t know, which is a valuable skill to have in life.
