Read the scenario below and answer the following questions.Remember to provide detailed responses. Note: Look at the datacarefully. You may have to do some calculations! You teach scienceto a class of 20 sixth grade students and at the end of a unit onecological interactions, you give a 100-point multiple-choice test.The test covers four areas: 1) how matter moves in food chains, 2)interpreting food webs, 3) using food chains to predict changes inpopulations, and 4) classifying symbiotic relationships. Here isthe list of scores: Student Total score (% correct) Sam 96 Kayti 72Jaime 92 Noah 68 Rashmi 92 Dela 68 Sofia 100 Suhaila 88 Tyler 68Zoe 84 Mark 68 Victor 96 Eugenia 60 Mickey 72 Candace 84 Willow 68Kirk 76 Chantal 68 Anna 100 Owen 92 Class Mean 80.6 You know thatstudents from this school have had trouble with test items onecological interactions on the state test in previous years, andyou’re wondering whether you need to do more teaching in the fourareas [1) how matter moves in food chains, 2) interpreting foodwebs, 3) using food chains to predict changes in populations, and4) classifying symbiotic relationships] or can move on to the nexttopic on ‘Conservation’. You take these scores to a few of yourcolleagues and ask them to take a look. You explain that youdesigned the test such that if a student gets a score of 80% orbetter, you are really quite confident that he or she understandsthe concepts. When a student’s score is lower than that, you feelthere is something they still don’t understand. One of yourcolleagues, James, points out that the mean (or average) for thesescores is 80.6. He says, “Hey! The mean score is greater than 80%.Your students did well in the test. You’ve done your job. I say youmove on to the next topic. There’re lots more science topics tocover!” Questions: 1. Do you agree with James? Explain why or whynot. (Write more than 50 words) 2. What other descriptivestatistical data would you need to have apart from the class mean?Why would that help you make a more well-informed decision ofwhether to move forward or re-teach some areas? (Write more than100 words) 3. After reviewing the chapters on descriptivestatistics, what are TWO important insights you have gained thatwill help you in your own professional practice dealing with data?(Write more than 100 words)
