Watch the videos below then answer these two questions: 1. Explain the difference between: mean, median and mode. How can you remember how they are different? Which one is the actual average? 2. Find the mean, median, mode and range of the following data set: 4,5,7,7,7,8,9,10,11,12,12 Click the links to watch each video: Mean, Median, Mode, and Range (Links to an external site.) How Do You Find the Mean of a Data Set? (Links to an external site.) How Do You Find the Median of a Data Set? (Links to an external site.) How Do You Find the Mode of a Data Set? (Links to an external site.) How Do You Find the Range of a Data Set? (Links to an external site.) What is the Mean of a Data Set? (Links to an external site.) What is the Median of a Data Set? (Links to an external site.) What is the Mode of a Data Set? (Links to an external site.)

Average = Mean = "typical" or "middle"=> central

Ex:

4+3+1+6+1+7

Arithmetic Mean- 4+3+1+6+1+7  over the amount of numbers in this case 6. So this fraction equals 22 over six or 3 and 2/3.

To find the Median order the numbers from least to gratest. the circle the middle number.

Ex: 0, 7, 50, 10,000, 1,000,000

Circle the 50 since it is on the middle

If there is two numbers in the middle circle both then find the middle in between both numbers.

Ex: 1, 1, 3, 4, 6, 7,

Circle the 3 and 4.

Find the halfway point in between, in this case, 3.5.

Mode is the number that shows up the most in a group of numbers.

Ex: 4, 3, 1, 6, 1, 7

The one shows up twice while the other numbers show up once.

Hope this helps. :)

Try the questions yourself.

If you need help friend me and I can help with the questions.

side xy = 10

sin(x) = 4/5

cos(x) = 3/5

tan(x) = 4/3

step-by-step explanation:

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
