Median of a distribution is the value of the variable which divides it into equal parts . In case of individual observations x_1,x_2 .. x_n , if the number of observations is odd, then median is the value of ((n+1)/2) th observation when the observations have been arranged in ascending or descending order of magnitude. In case of even number of observations median is the A.M. of the values of (n/2) th and (n/2+1) th observations, arranged in ascending or descending order of magnitude . The mode of distribution is that value of the variable for which the frequency is maximum . Median of the distribution 25,20,11,3,12,18,17 ,9,21,22 is

50 " mL of " water on titration with standard soap solution gave the following results: Lather factor =0.4 mL, total hardness (TH)=8.2mL , permanent hardness (PH) =2.5mL and standard hard water (containing 0.2 g CaCO_3L^(-1))=19.9mL . Calculate each type of hardness in ppm.

This interference film is used to measure the thickness of slides, paper, etc. The arrangement is as shown in fig. For the sake of clarity, the two strips are shown thick. Consider the wedge formed in between strips 1 and 2. If the interference pattern because of the two waves reflected from wedge surface is observed, then from the observed data we can compute thickness of paper, refractive index of the medium filled in wedge, number of bonds formed, etc. Considre the strips to be thick as compared to wavelength of ligth and light is incident normally. Neglect the effect due to reflection from top surface of strip 1 and bottom surface of strip 2. Take L = 5 cm and lambda_(air) = 40 nm . For data in question53 determine the distance of point B from the 20th dark band. Counting of dark point has to start from the contact point.
