Which of the four graphs has the greatest standard deviation? please help me ​
Norma-Jean [14]

Answer:

  • Standard deviation is how far away the values are from the mean.
  • All of your graphs have normal distribution, meaning the mean is in the center.

<em>The more spread out your graph is, the greater the standard deviation.</em>
