What reading level is An Introduction to Statistical Methods a Textbook for College Students a Manua book?
To quickly assess the difficulty of the text, read a short excerpt:
17, the median is still $4. 00 as in the case without these exceptional numbers. The arith- metic average, however, is changed from $2. 67 to $3, 660. 39.
In dealing with discrete scries, one should rarely attempt to compute exact medians. Too great accuracy may result in making this average; nothing more than a mathematical concept, ill suited to the units in which the data are expressed; and one wholly determined by the relation of the two middle terms. In continuous series the problem is dif...ferent, inas- much as the data u. Sed arc generally samples and serve only more or less imperfectly to describe an ideal distribution. The median, of course, may be used in discrete series, but care should be taken not to assign too definite a position to it by refined methods of interpolation.
When data arc arranged in frequency groups, the problem of determining the median is the same as it is when they are not grouped, except that it is necessary arbitrarily to distribute the frequencies within the groups in order to inter- polate for the exact median.
