A Year 6 lesson slide teaching problem solving and finding the mean on Third Space Learning’s online intervention. Instead, the non-statutory guidelines state that pupils should know when it is appropriate to find the mean of a data set. There is no longer a requirement for median, mode and range to be taught at the primary phase of school.Īlthough mean is compulsory in Year 6 and comes under the statistics section of the national curriculum for mathematics, where it states that ‘pupils should be taught to calculate and interpret the mean as an average.’ Median and mode are not part of the national curriculum in the UK. When do children learn about mean median mode? To find the difference, you need to subtract the highest value from the lowest value. With our data set that would be 11, as the highest number is 15 (Yahyah) and the lowest number is 4 (Christine). The range is the difference between the highest and lowest values. When your data set contains an even number of values rather than an odd number, take the pair of numbers that would make the median, add them together and then divide them by 2. The middle value, or median, is 7 as there are an equal number of other values on either side of the second 7. Once that is done, our data looks like this: That means we take the data values from the table and write them out in ascending order. Remember that the data needs to be placed into value order. The median value is found by finding the middle value. Mode shares some similar orthography with the word ‘most’ which can be a useful way to get pupils to remember how to find the mode. With our set of numbers, the mode would be 7 as this appears twice in our data in the table above. This is one way you can remind pupils how to find the mean of a number of data points! Finding the mode With bigger numbers, pupils can use partitioning to help them with the calculations.ĭue to the amount of calculating involved in finding the mean, it is referred to as the ‘meanest’ of the averages. Taking the above data as an example, to find the mean you would need to add 7, 12, 15, 7 and 4 together to get 45 and then divide this by the number of values, in this case, 5. To calculate the mean, median, mode and range, we need to manipulate this data using the information about how to find each particular average above. The following data set is from a game a group of pupils were playing in the classroom. To find an average, you must first have a data set. This time-saving worksheet is for Year 6 pupils and includes 4 arithmetic questions, 9 consolidation questions, and 1 challenge question. For example, when dealing with data that contains outliers, finding the mean may not always be the best option. Introducing the concepts at this stage proves useful in later years. It is useful for pupils to be aware of mean, median, mode and range despite it not being an explicit requirement. Mean median mode and range in the national curriculum The number you are left with is your range. To calculate the range, take away the smallest value in your set of values from the largest. The range is the difference between the largest value and the smallest value. You can use a frequency table to work this out. So identify how many number of numbers appear in your dataset, and which particular number appears most often. The mode is the value that appears the most number of times in a set of data. The median is the number that is in the middle of the list of numbers. So list the numbers in your dataset from the lowest value to the highest value. The median is the middle value (or midpoint) when a data set is ordered from least to greatest. It is also known as ‘arithmetic mean’, but NOT a ‘geometric mean’. It can be calculated by adding up all of the numbers in the data set and then dividing by the total number of values in the set. Mean mode and medium are different types of averages from a data set. Find out what mean, median, mode and range are, when they are taught in school, and how you can help children to understand them as part of their maths learning at home.īefore the 2014 curriculum reforms, pupils were expected to learn about all 4 different types of averages and solve problems based on their application. But now the national curriculum only has ‘mean’ as a type of average that pupils need to be explicitly taught in Year 6.ĭespite this, some schools continue to teach all four different averages after Year 6 have completed their end-of-year assessments.
