2, question 2: 2. Some Grade 5 learners did an experiment to see how many counters they could pick up in one hand. These are their results: | Learner | Counters | Learner | Counters | Learner | Counters | Learner | Counters | Learner | Counters | |---|---|---|---|---|---|---|---|---|---| | Vusi | 18 | Pumla | 18 | Carol | 17 | Mandy | 12 | Palesa | 11 | | Tiny | 16 | Sihle | 13 | Jess | 18 | Josh | 16 | Nina | 18 | | Noni | 15 | Kobus | 15 | Peter | 14 | Simeon | 18 | Helene | 17 | | Petrus | 17 | Ziggy | 18 | Saul | 16 | Zanele | 12 | Julius | 12 | a) Arrange the results in order from smallest to largest. Step 1: List all the numbers of counters: 18, 18, 17, 12, 11, 16, 13, 18, 16, 18, 15, 15, 14, 18, 17, 17, 18, 16, 12, 12. Step 2: Arrange them in ascending order. 11, 12, 12, 12, 13, 14, 15, 15, 16, 16, 16, 17, 17, 17, 18, 18, 18, 18, 18, 18 b) How many learners could hold less than 15 counters? Step 1: From the ordered list, identify numbers less than 15: 11, 12, 12, 12, 13, 14. Step 2: Count these numbers. 6 learners c) How many learners could hold 16 or more counters? Step 1: From the ordered list, identify numbers that are 16 or greater: 16, 16, 16, 17, 17, 17, 18, 18, 18, 18, 18, 18. Step 2: Count these numbers. 12 learners d) What is the modal number of counters? Step 1: Identify the number that appears most frequently in the ordered list. The number 18 appears 6 times, which is more than any other number. 18 counters e) Which learners picked up the modal number of counters? Step 1: Identify the learners who picked up 18 counters from the original table. Vusi, Pumla, Jess, Nina, Simeon, Ziggy That's 2 down. 3 left today — send the next one.
