You can often detect bad fish easily by smell or touch, but that's not always the case.nfortunately it's also a spectacularly perishable food, and just a day or two in your refrigerator -- or an unplanned stop on your way home from the store -- can spoil your meal.

In analog frequency modulation, such as FM radio broadcasting of an audio signal representing voice or music, the instantaneous frequency deviation, the difference between the frequency of the carrier and its center frequency, is proportional to the modulating signal.
The relative frequency histogram gives the fraction of times the data occur in the particular group or interval. Relative frequency distribution of a class is the ratio of the frequency of the class to the total number of the items.A uniform distribution often means that the number of classes is too small, each class has about the same number of elements. It may describe a distribution which has several peaks.he relative frequency table is a compact numerical way to present how the data is distributed. If the frequencies are plotted as columns, the resulting plot is called a histogram. A frequency distribution shows the number of items in each of several overlapping classes.
