Which of the following statements are true? Check all that apply. - The mean is affected by outliers. - The mean is not always a more accurate measure of center than the median. - Removing an outlier from a data set will cause the standard deviation to decrease. - If a data set’s distribution is skewed, then 95% of its values will fall within two standard deviations of the mean. - If a data set’s distribution is skewed to the right, its mean will be larger than its median.

Which of the following statements are TRUE about the Normal Distribution? Check all that apply. The mean, median, and mode are all equal and occur at the center of the distribution. The graph of the Normal Distribution is bell-shaped, with tapering tails that never actually touch the horizontal axis. Data values are spread evenly around the mean. Data values farther from the mean are less common than data values closer to the mean. The distribution is symmetric with a single peak. 50% of the data values lie at or above the mean. About 95% of all data values lie within 1 standard deviation of the mean.

Which of the following statements are true about measures of centre and measures of spread ? You may choose more than one answers. Group of answer choices - Median and IQR are usually better for describing a skewed distribution or a distribution with outliers. - The sample mean and standard deviation are not resistant to outliers and skewness. - If the distribution is exactly symmetric, the mean and the median are exactly the same. - Sample mean and standard deviation are usually better for describing a skewed distribution or a distribution with outliers.

Determine whether each statement is true or false. The median is equal to the second quartile.
