 Hello and welcome to the session. In this session we discuss the following question which says constructive frequency table for the following. The observations are 3, 2, 5, 4, 1, 4, 2, 3, 4, 6, 5, 3, 1, 4, 2, 4. Let's move on to the solution now. The observations are 3, 2, 5, 4, 1, 4, 2, 3, 4, 6, 5, 3, 1, 4, 2, 4. Now that we need to construct a frequency table, so for that first we will arrange the given data in an ascending order. So we have to arrange the given data in an ascending order. Now we will put this data in a tabular form. So in this table we have the observations, the tally marks and the frequency for the corresponding observations. These are the observations 1, 2, 3, 4, 5 and 6. Now in the given data we see that 1 occurs 2 times. So we will put 2 tally marks and as 1 occurs 2 times so its frequency would be 2. Now consider the observation 2. It occurs 3 times as given in the data. So we will put 3 tally marks and so its frequency would be 3. Then consider the observation 3. It occurs 3 times as you can see in the given data. So we have 3 tally marks with the observation 3 and so its frequency is also 3. Now consider the observation 4. It occurs 5 times. To represent 5 using the tally marks we put 4 tally marks vertically and we put a cross like this to show the 5th tally mark and so its frequency is 5 since it occurs 5 times. Now consider the observation 5. It occurs 2 times and so we will put 2 tally marks and its frequency is 2. Now consider the observation 6. It occurs 1 time so we will put 1 tally mark and its frequency is 1. So this is the frequency table for the given data. With this we complete the session. Hope you have understood the solution of this question.
