Question

question 24 points 1

the smaller the standard deviation, the data is ________ concentrated.

more
less

Explanation:

Define standard deviation

Using the Standard Deviation and Measures of Spread knowledge points

$$ \sigma = \sqrt{\frac{1}{N}\sum_{i=1}^{N}(x_i - \mu)^2} $$

Analyze the relationship with concentration

Using the Standard Deviation and Measures of Spread knowledge points

  • A smaller standard deviation means individual data points \(x_i\) are closer to the mean \(\mu\).
  • Therefore, the data points are more clustered or concentrated around the center.

Answer:

  • more (Correct answer)
  • less
