 D Level 6 Focus: Describing scatterplots escribing Scatterplots This resource contains 15 pages of scatterplots. Most have a short story with the variables listed and the data set given. This is usually on one page. On a second page are the title, variables and then the scatterplots. With each graph(s) there is the starter: What we notice about the graph(s): The main aim of this activity is to get students to describe what they see in the graphs before they get hung up on drawing lines of best fit, making calculations or in fact have much in the way of analysis tools. Trying to get through to them the need to draw the graph first. Plan Photocopy the pages for use in class. The write-on pages need to be copied multiple times, the story pages only once. Make about eight copies of each write-on page. (64 activities, standard class 15 pairs @ 4 each is 60 activities) Set up the different stories around the class. Split the class into pairs. Each pair should endeavour to do at least 4 different stories. (allow about 5 mins per story then move to next one) Suggested groupings might be: Pair 1 do 1, 2, 3, 4 Pair 2 do 2, 3, 4, 1 Pair 3 do 2, 3, 4, 5 Pair 4 do 3, 4, 5, 2 Pair 5 do 3, 4, 5, 6 Pair 6 do 4, 5, 6, 3 Pair 7 do 4, 5, 6, 7 Pair 8 do 5, 6, 7, 4 Pair 9 do 5, 6, 7, 8 Pair 10 do 6, 7, 8, 5 Pair 11 do 6, 7, 8, 1 Pair 12 do 7, 8, 1, 6 Pair 13 do 7, 8, 1, 2 Pair 14 do 8, 1, 2, 7 Pair 15 do 8, 1, 2, 3 Pair 16 do 1, 2, 3, 8 At the end the pairings will join up to compare and contrast what they have found (that is why the pairs are not doing the same activity at the same time). Pair 1 and 2 together etc. Any additional pairs double up. Data Smoking and cancer (2 pages – 1 write-on) World population figures (2 pages – 1 write-on) Olympic games long jump gold medal (2 pages – 1 write-on) High jump world records men (2 pages – 1 write-on) Global mean temperatures (3 pages – 1 write-on) Alligator (1 write-on page) Cattle (1 write-on page) Body fat (2 pages – 1 write-on) Analysis Focus in this activity is on the analysis of the graph, initial not icing’s that students do. Get pairs of students to compare and contrast with another pair of students who have done the same activity. Conclusion Reflection Extension activity
