Your class just took your last math test of the year these are the scores 97 99, 81, 78, 73, 95,33, 97,64, 100, 85, 83, 85, 88, 79, 81, 93, 86, 83, and 71. What is the mean, median, and mode of the data ?

Step-by-step explanation:

1. Put them in order from least to greatest first

33, 64, 71, 73, 78, 79, 81, 81, 83, 83, 85, 85, 86, 88, 93, 95, 97, 97, 99, 100

2. Mean

Add them all, the divide the sum by the total number of grades

33+64+71+73+78+79+81+81+83+83+85+85+86+88+93+95+97+97+99+100= 1566

1566/20= 78.3

3. Median

Find the number in the middle, if there's two, add them and divide by two

83+85= 168

168/2= 84

4. Mode

Find the numbers that reoccurs the most

81, 83, 85, 97

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )
