Calculate variance and co-efficient of variation from the following data: Class Interval : 12-16 16-20 20-24 24-28 28-32 32-36 Frequency: 2 8 18 10 6. 5
: 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.
