A pile of 35 answers is hard to read. So the first job is always to sort the answers into groups and count each group . Nine friends said half an hour, thirteen said one hour, seven said one and a half hours, three said two hours and three said two and a half hours. 9 + 13 + 7 + 3 + 3 = 35. The count is complete. A table is the first picture of data. A table has two columns: what you counted on the left, how many on the right. Once the 35 answers sit in a table you can read anything off it in a second — which group is biggest, which is smallest, how many in two groups together. A pictograph shows data with small
