Positively skewed: Mean > Median > Mode |

negative skewed distribution means that it has long tails on the negative side ( left) and short tail on the positive side (right). |

Good hint "while skewing a distribution to left / right you're pooling the mean to the same direction and the mode remains at the same position" |

negatively skewed = mean< median< mode. positively skewed = mode< median< mean. |

Regardless of which way it is skewed, the median is always in the middle (think of it alphabetically), so only C can be right in this case. |

The mode is the most frequent (or most common) observation so it will always appear at the "crest" of the curve, the highest part of the bump. Median is the middle observation, hence it is in the middle. This might help to remember the order. |

And the mean is always pulled furthest towards the direction of skewing (to the far left in the case of a negatively skewed distribution) |

Positively skewed: Mean > Median > Mode Negatively skewed: Mean < Median < Mode Isn't the correct answer C then instead of B? |
