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
