I'm not sure if you know how to work out mode, median and mean but I'll explain anyway.
I'll start with the mode as I think it's the easiest. The mode is the number that appears the most. In this case 58. That's your answer. Simple as that. 58 appears twice and the rest only once. I remember mode by it looks similar to most. Mode, most. Median- First order the numbers in size. 58, 58, 75, 86, 94, 97 Now cross off each side until you get to one or two left I'm the middle. If there are a equal number of numbers cross off til you get to the middle two. If there's a odd number of numbers cross off til there's only one left. In this case we have six so we will cross off til there's two left in the middle. The numbers are 75 and 86. Since you need one number and we have two, you'll have the work out the number inbetween 75 and 86, which is 80.5. The answer is 80.5. I remember this by median sounds like medium and your finding the number in the middle. Mean. First add up all of marias scores. 86+75+97+58+94+58=468. Now divide by how many numbers there are. 468 divided by 6 is 78. So it's 78. I remember this by this is the hardest to do so it's 'mean' To recap: Median: 80.5 Mode: 58 Mean: 78 As for B, she would use the mode because it's the lowest number and if Maria thinks she's doing really bad she'll revise. Hope it helps! ![]() |
