(8) Define a Histogram. How is It constructed? What Information may be deduced? Solution: A histogram is a two dimensional diagram. It is a set of rectangles with base as the intervals between class boundaries (along X-axis) and with areas proportional to the class frequency (I) Histogram: A graphical display of data using bars of different heights. Or A histogram is a bar chart or graph showing the frequency of occurrence of each value of the variable being analysed. (ii) Construction of Histogram: In histogram, data are plotted as a series of rectangles. Class intervals are shown on the 'X-axis' and the frequencies on the '111-axis'. The height of each rectangle represents the frequency of the class interval. Each rectangle is formed with the other so as to give a continuous picture. Such a graph is also called staircase or block diagram. However. we cannot construct a histogram for distribution with open-end classes. It is also quite misleading if the distribution has unequal intervals and suitable adjustments in frequencies are not made. (III) Information received from Histogram: It is the method of presenting data. In this we can the quickest understanding the actual situation it also helps to explained by data. Diagrammatic presentation of data translates quite effectively the highly abstract ideas. Usefulness of Histogram: (a) Histogram gives value of mode of the frequency distribution graphically. (b) Frequency polygon can be derived from histogram. (c) Histogram helps to studying the shape of the curve.
(C) Look at this serles:E2 Dli.C16.832.what number should MI the blank? Solution : E4 Explanation: Isolate the letter and the number from each of the units of the series. The two seem to form two different series of their own. The letters seem to be heading backwards — 'F. _ D. C, B. A' Going by logical sense the missing alphabet is E' Now observe the series of numbers, they follow the following pattern. 2, _ , 8. 16, 32' Now the missing number is '4' Therefore E and 4 = E4 (3) In a certain code language LAND:MINE is written as Pi'REQGRC .How will HOMEMADE be written In that code language?
