Answer:
mode = 1 , median = 2 and mean = 3
Step-by-step explanation:
Here, we want to get the mean , median and the mode
1. Mode
The mode deals with the number which has the highest frequency. Looking at the table, the number with the highest frequency is 1
2. Median
The median deals with the middle number, given that the numbers were arranged from lowest to highest or highest to lowest. The count of frequency is 15 and this mean that the middle number is the 8th term.
With the given arrangement, The 8th term falls within the number 2
3. Mean
The mean is the average. The arithmetic mean is the sum of the numbers divided by their count
the sum of the numbers is;
1(7) + 2(3) + 3(1) + 5(2) + 8(1) + 11(1) = 45
The count of the numbers is the sum of the frequencies = 15
the mean is thus;
45/15 = 3
So therefore;
mean = 3
mode = 1
median =2
