Here are the calculations based on the provided scores: 60, 90, 60, 60, 72, 80, 60, 80. Step 1: List the scores and calculate the total score. The scores are 60, 90, 60, 60, 72, 80, 60, 80. The number of scores is 8. Total score = 60 + 90 + 60 + 60 + 72 + 80 + 60 + 80 = 562 The total score is 562. Step 2: Calculate the average mark. The average mark is the total score divided by the number of scores. Average mark = Total scoreNumber of scores = (562)/(8) = 70.25 The average mark is 70.25. Step 3: Find the median mark. First, arrange the scores in ascending order: 60, 60, 60, 60, 72, 80, 80, 90 Since there is an even number of scores (8), the median is the average of the two middle scores (the 4^th and 5^th scores). The 4^th score is 60. The 5^th score is 72. Median mark = (60 + 72)/(2) = (132)/(2) = 66 The median mark is 66. Step 4: Find the mode. The mode is the score that appears most frequently. In the sorted list 60, 60, 60, 60, 72, 80, 80, 90: The score 60 appears 4 times. The score 72 appears 1 time. The score 80 appears 2 times. The score 90 appears 1 time. The score that appears most frequently is 60. The mode is 60. Step 5: Find the range. The range is the difference between the highest and lowest scores. Highest score = 90 Lowest score = 60 Range = Highest score - Lowest score = 90 - 60 = 30 The range is 30. Send me the next one 📸
