Based on the above graph, answer the following questions:
(1) Form the frequency distribution table for the data.
(ii) Find the median marks of his class from the graph and verify the result by using formula.​

Answer 1

Steps to make a frequency distribution table is given below.

Step-by-step explanation:

Steps are:

1. Make a table with marks and frequency in the first row of the table.
2. Make it in the interval of 10-20, 20, 30 etc. till 110. Now, write down the students who got marks in the respective interval in the frequency column.
3. Hence, the table is formed.

Median can be calculated by arranging the marks in ascending order.

     For even nos.

                          =  $\frac{total \\ no.}{2}$

       for odd nos.

                  = $\frac{total \\ no. + 1}{2}$

Answer 2

Answer:

Step-by-step explanation:

Data science is an inter-disciplinary field that uses scientific methods, processes, algorithms and systems to extract knowledge and insights from many structural and unstructured data. Data science is related to data mining, machine learning and big data.
