Find the
means
median and mode
mode of
the following
23, 34, 27, 31, 34, 18, 34
Answers
Answer:
Mean = 28.71 (2sf)
Median = 31
Mode = 34
Step-by-step explanation:
Mean:
Mean = Sum of terms/Number of terms
23 + 34 + 27 + 31 + 34 + 18 + 34 = 201
201 (Sum of terms) /7 (Number of terms) = 28.71 (2sf)
Median:
1) Line up numbers in order (smallest to largest)
18, 23, 27, 31, 34, 34, 34
2) The median is the middle number in a sorted list.
Therefore, the middle number, in this list, is clearly 31.
Mode:
The mode is the most frequent number.
If we look at our list, the most frequent number is 34 - as it appears 3 times.
Therefore, 34 is our mode.
Answer:
Median: 18
Mode: 34
Mean:
Step-by-step explanation:
Lets find the Median first.
So first we need to arrange the numbers 23, 34, 27, 31, 34, 18 and 34
Arranged form: 18, 23, 27, 31, 34, 34, 34.
Here the middle number is 18, so 18 is our median.
Lets move on to Mode.
So mode is the most common number in the group.
In 18, 23, 27, 31, 34, 34, 34, the most common number is 34 as it appears 3 times, so our mode is 34.
The last one is Mean.
Mean is the sum of all the numbers ÷ how many numbers there are.
The sum of 18, 23, 27, 31, 34, 34, 34 is 201.
Now 201 ÷ 7 = 28.7.
Hope this helps!
