For the frequency distribution: Variate \((x): x_1 x_2 x_3 \ldots x_{15}\) Frequency \((f): f_1 f_2 f_3 \ldots f_{15}\) …

For the frequency distribution:
Variate \((x): x_1 x_2 x_3 \ldots x_{15}\)
Frequency \((f): f_1 f_2 f_3 \ldots f_{15}\) Where \(0<x_1<x_2<x_3<\ldots<x_{15}=10\) and \(\sum_{i=1}^{15} f_i>0\), then standard deviation cannot be:
