Question

calculating mean
complete the statements about calculating mean using the data set 4, 6, 1, 9, 12, 3, 11, 2.
first, add the values in the data set. the sum is
the mean, or average, is found by dividing this sum by
the mean is
5
6
7
8

Explanation:

Step1: Sum the data values

Add the numbers: \(4 + 6 + 1 + 9 + 12 + 3 + 11 + 2\)
\(4+6 = 10\), \(10+1 = 11\), \(11+9 = 20\), \(20+12 = 32\), \(32+3 = 35\), \(35+11 = 46\), \(46+2 = 48\)

Step2: Determine the number of values

Count the data points: 4, 6, 1, 9, 12, 3, 11, 2. There are 8 values.

Step3: Calculate the mean

Divide the sum by the number of values: \(\frac{48}{8}=6\)

Answer:

The sum is \(48\).
The mean is found by dividing this sum by \(8\).
The mean is \(6\).
