Analysing and interpreting data

By: Zani AlamLearning intention:To learn what is mean, mode, median and rangeTo find the mean, median, mode and range and ebe able to explain to others using examples.

Once upon a time Mrs Lee gave her students a data quiz.

The table below shows how many answers each student got correct on a quiz of 10 questions.

Then Mrs Lee asked her students to find the mean, median, mode and range of this data collection.The story of the dayNameScoreRana7Mariam8Lisa9Yasmine10Lesley7Valentina7Reem7Sarah6Fill in the vocabulary activityFirst column only and the rest for homeworkYou are given 3 minutesMean, Median Mode and Range MiddleAverageMost frequentDifferenceMatch each word in the left column with the correct statistics term on the right.

A . To find the Median . Each player finds the median card in their hand. ( The number is their point value for that round). B. To Find the Mean . Each player finds the total value of the digits on their cards, then divides the total by 7 (the total number of cards with each player) .(This represents their point value for that round).

C. To Find the Mode . Each player finds the most occurring card in their hand.(This represents their point value for that round). If there is no mode, then they dont score any points in that round. If there are two modes, the sum of the two numbers is the point value.D. To find the Range . Each player finds the range and the number is the point value for that round. The winner of the game is the first person who scores 25 points.
