1 Shiny and dry surface-when it starts going bad, it gets a slimy greyish coating. 2  Fresh odour-it can also smell like melon or cucumber. 3  If it's bad, it will smell rotten, like a sour dishcloth. 4  An even, light surface-the fish is bad if it has yellow spots and transparent parts on the surface.he fish you buy in the shops isn't always as fresh as it should be. But it can be difficult to ascertain when the fish actually starts going bad.

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.
