: Which one of the following statements is True? The units of the Variance are the same as the original data. The Mean can be found from a Box Plot. Relative Frequency equals Frequency multiplied by Total Frequency. An Ogive chart increases in height from left to right. For a unimodal mound shaped distribution that is Skewed Left the Mean is greater than the Median.

Given the sales figures of all the stores across the United States, Jerry calculates the following statistics: Mean: the average of the sales figures. Median: the value separating the higher half from the lower half of the sales figures Mode: the number that occurs most frequently in the data Variance: it measures how far the sales figures are spread out from their average value Jerry recalls the implications of the statistics. Which one of them is correct? Select one: II
In one-way analysis of variance, the F ratio is computed by: Select one: a. dividing the sum of squares between groups by the sum of squares within groups O b. dividing the sum of squares within groups by the sum of squares between groups O c. dividing the mean square between groups by the mean square within groups O d. dividing the mean square within groups by the mean square between groups
Consider a data set containing the following values: 60 93 84 80 95 99 78 90 The mean of the preceding values is 84.875. The deviations from the mean have been calculated as follows: -24.875 8.125 -0.875 -4.875 10.125 14.125 -6.875 5.125 If this is sample data, the sample variance is and the sample standard deviation is If this is population data, the population variance is and the population standard deviation is Suppose the smallest value of 60 in the data was misrecorded as 75. If you were to recalculate the variance and standard deviation with the 75 instead of the 60, your new values for the variance and standard deviation would be
