1 (a) Mean is the approrpriate measure for interval data
(b) range, interquartile range, variance, standard deviation, and coefficient of variation are the appropriate measures of variability for interval data
(c) Quartiles and percentiles are appropriate measures of relative standing for interval data
2. To the researcher, the population of Interest is the women in the vlllage, the relevant populatlon data are the heights of women in the village, and the populatlon parameter of Interest is the population mean .
For 350 women, the sum of the heights = 532.3 metre.Their average height = 532.3/350 = 1.52 metres
The sample for his estlmatlon is the 25 village women . The relevant sample data are the heights of the 25 village women , and the sample statlstlc is the sample mean
If the sum of the heights of the 25 village women is 38.9 metres, their average height is 1.556 metres.
