The following outcomes were recorded when a dice was thrown 30 times

Question

2,3,5,4,4,3,5,1,4,3,1,1,4,2,3,5,1,4,2,2,3,2,1,5,5,2,1,3,5,1
a. Prepare the frequency table for the data above
b.find the mean of the data
c.find the mode

Answer 1

a. Frequency table:

Number | Frequency
-------|----------
1 | 7
2 | 6
3 | 5
4 | 6
5 | 6

b. Mean:

To find the mean, add up all the numbers and divide by the total number of throws:

(2+3+5+4+4+3+5+1+4+3+1+1+4+2+3+5+1+4+2+2+3+2+1+5+5+2+1+3+5+1) / 30
= 93 / 30
= 3.1

So the mean is 3.1.

c. Mode:

The mode is the most commonly occurring number, which in this case is 1 (which occurred 7 times). So the mode is 1.
