64 + ? = 96
64 + 32 =96
Answer: mean =54.69
Median = 61.5
There is no mode
Step-by-step explanation:
Mean is calculated as sum of values in a data set/ number of values in a data set.
Given the data set above,
mean=54.6+45.98+67.4+55.6+45.7+58.9/6
=328.18/6
Mean= 54.69
Median is the midpoint of the values in a data set. For an even data set, however, median is the sum of two middle values divided by two.
To find the median, we sum the two most middle values= 67.4 and 55.6; then divide by two
Median = 67.4 + 55.6/2
= 123/2
Median = 61.5
Mode is the value with the highest occurrence in a data set. In the given data set, there is no mode, as all data values appear once.
