Answer: A.) mean = mode
Step-by-step explanation:
The given data : -1, -1, 0, 1, 1, 1, 1, 2, 2, 2, 3
Number of terms = 11
[tex]\text{Mean=}\dfrac{\text{Sum of all observations}}{\text{Number of observations}}\\\\\Rightarrow\ \text{Mean=}\dfrac{11}{11}=1\\\\\Rightarrow\ \text{Mean=}1[/tex]
Since the data is already arranged in order.
Median = Middle-most value=1
Hence, Mean=Median
Mode = Most repeated observation=1
i.e. Mean=Median=Mode
