The name of that mineral-rich silt is loess. In fact, this extensive Chinese river is called Huang ("Yellow") due to the great amounts of fine loess deposits that it carries to the Bohai Sea and that turn the water that color. It is not infrequent that, as a result of these thick loess sediments, the course of the river changes, and that the bed of the river is so elevated as to cause devastating, and often deadly, floods.
The relative frequency distribution is <u>0-60 (6.45%).</u>
<u>Explanation</u>:
A relative frequency is calculated by the fraction or proportion of number of times the occurrence of a value. The fraction of each frequency to the total number of data points in the sample expresses the relative frequencies. Relative frequencies can be written in the form of fractions, percent or decimals.
The frequency distribution table shows how often the event happens. The following are different types of frequency distribution:
i) Grouped frequency distribution
ii) Ungrouped frequency distribution
iii) Cumulative frequency distribution
iv) Relative frequency distribution
v) Relative cumulative frequency distribution
