Ravipal Reddy Director, SIGMA, Hyderabad Data Interpretation Bar charts Bar charts are a type of graph that are used to display and compare the number, frequency or other measure for different discrete categories of data. Bar charts are one of the most commonly used types of graph because they are simple to create and very easy to interpret. They are also a flexible chart type and there are several variations of the standard bar chart including horizontal bar charts, grouped or component charts, and stacked bar charts. The chart is constructed such that the lengths of the different bars are proportional to the size of the category they represent. The X-axis represents the different categories and so has no scale. In order to emphasis the fact that the categories are discrete, a gap is left between the bars on the X-axis. The Y-axis does have a scale and this indicates the units of measurement. Directions (Q No. 1 – 5): Study the given graph carefully to answer the questions that follow.

Rajendra Senior Faculty Hyderabad Unit- III, IV & V of Second year In the last and concluding part of the series of EAMCET model papers, in the second year syllabus Unit-III , Unit-IV and Unit-V is being discussed. All are of the related topics dealing with classical and molecular genetics. Some subsections of Molecular genetics are a new addition to the old syllabus. Both long term and regular students feel difficult to understand these chapters. Most of the question will be knowledge based and easy questions. Problems on DNA and genetics is a regular feature in EAMCET exams. One or two problems may be given from these units. Practice is essential for this type of questions to save time on solving the questions. In Biotechnology part of the syllabus not more than one question can be expected whereas in the application part knowledge based questions can be asked. Model questions: 1.
