Answer:
Fictional dataset: [12, 18, 15, 22, 18, 25, 12, 16, 22, 25]
Mean: 18.5
Median: 18
Mode: No mode
Range: 13
Step-by-step explanation:
Mean:
Mean = Sum of all values / Number of values
Mean = 12+18+15+22+18+25+12+16+22+25 / 10
Mean = 185/10
Mean=18.5
Median:
Arrange the dataset in ascending order: [12, 12, 15, 16, 18, 18, 22, 22, 25, 25]
Since there are 10 values, the median is the average of the 5th and 6th values.
Median = 18+18/2
Median = 18
Mode:
The mode is the value(s) that occur most frequently.
In this case, there is no mode as all values occur only once.
Range:
Range = Maximum value − Minimum value
Range=25−12
Range=13
