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.

Step 1: The first true statement is that median and IQR are usually better for describing a skewed distribution or a distribution with outliers because they are less affected by outliers. Show more…

Which of the following statements are TRUE about the Normal Distribution? Check all that apply. About 95% of all data values lie within 1 standard deviation of the mean. Data values farther from the mean are less common than data values closer to the mean. 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. 50% of the data values lie at or above the mean. The mean, median and mode are all equal and occur at the center of the distribution. The distribution is symmetric with a single peak.

Determine which of the following are true and which are false. Then, in complete sentences, justify your answers. a. When the sample size is large, the mean of $\overline{X}$ is approximately equal to the mean of $X .$ b. When the sample size is large, $\overline{X}$ is approximately normally distributed. c. When the sample size is large, the standard deviation of $\overline{X}$ is approximately the same as the standard deviation of $X .$
