Practice Other Topics from Data Handling
This topic covers computation and reading of data from a bar graph and the understanding of scales. It explains how to decide an appropriate scale and draw single and double bar graphs for a given set of data.
This topic highlights the ways to organise data. It also explains the importance of raw data, frequency and the frequency distribution table with aid of examples.
This topic explains the relevance of grouped frequency distributions for a set case. Following this, the terms used, and the process of grouping is explained. This is followed by a depiction of this data graphically, in the form of a histogram.
In this topic, a circle graph shows the relationship between a whole and its parts. Here, the whole circle is divided into sectors. The size of each sector is proportional to the activity or information it represents.
This topic covers chance and probability. Probability is a numerical description of how likely an event is to occur or how likely it is that a proposition is true.
