What is a grouped frequency table | a visual depiction of data that reports the frequencies within a given interval rather than the frequencies for a specific value |

What is a normal distribution | a specific frequency distribution that is a bell shaped symmetric uni-modal curve |

What does positively skewed mean | the distribution tail extends to the right in a positive direction |
