|| ||  **Answer: ** The required histogram representing the given data is shown in graph.
 * ** Date ** || ||
 * ** Class ** || SS 3 ||
 * ** Time ** || 9:00 – 10:00 ||
 * ** Duration ** || 1 hour ||
 * ** Subject ** || Mathematics ||
 * ** Topic ** || Grouped Data ||
 * ** Instructional Resources ** || Computers, White Boards, Students ||
 * ** Specific Objectives ** || At the end of the lesson, the students should be able to: 1. Draw a frequency Distribution table 2. Draw a Histogram ||
 * ** Previous knowledge ** || The students know how to draw bar Charts, pie Charts Using the Computer. ||
 * ** Introduction ** || Teacher introduces the lesson ||
 * ** Presentation ** || Teacher presents the lesson in steps ||
 * ** Step 1 ** || Teacher identifies grouped data as one that is too much to deal with individually. Example1. The heights of 36 students in a class is given as :  146, 148 149 150 151 153 154 155 155 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 172 173 174 176 177 178 179 180 181 183 183 185 ||
 * ** Step 2 ** || Teacher gives an example of drawing a frequency distribution table || ** Class interval ** || ** frequency ** ||
 * 145 – 154 || 6 ||
 * 155 - 164 || 9 ||
 * 165 - 174 || 15 ||
 * 175 – 184 || 5 ||
 * 185 – 194 || 1 ||
 * ** Step 3 ** || Teacher explains drawing oh histogram || ** Class interval ** || ** frequency ** || ** Class boundary ** ||
 * 145 – 154 || 6 || 144.5 - 154.5 ||
 * 155 - 164 || 9 || 154.5 -164.5 ||
 * 165 - 174 || 15 || 164.5 - 174.5 ||
 * 175 – 184 || 5 || 174.5 - 184.5 ||
 * 185 – 194 || 1 || 184.5 -194.5 ||
 * || Frequency is plotted against class boundary. ||
 * ** Evaluation ** || Teacher refers student to Question Bank ||
 * || Question 1 **Question: ** By using a of scale 1cm=10%, draw a histogram of the following data:

 Question 2 **Question: ** Draw a histogram of the following frequency table.   **Answer: ** On the basis of data, we will first prepare the table of continuous classes and then draw the required histogram.

||  ||
 * ** Conclusion ** || The lesson of the day is on Grouped Data and the use of frequency distribution in drawing the Histogram. ||
 * ** Assignment ** || Teacher refers question bank for assignments. ||
