Question

a dice was thrown 30 times and the following outcomes were noted
2,1,2,4,6,1,2,3,6,5,4,4,3,1,1,3,1,1,5,6,6,2,2,3,4,2,5,5,6,4
prepare a frequancy table.​

Answer 1

Given :

• A dice was thrown 30 times and the following outcomes were noted 2,1,2,4,6,1,2,3,6,5,4,4,3,1,1,3,1,1,5,6,6,2,2,3,4,2,5,5,6,4

Have to make :

• Frequency Table

The frequency table for the given information :

            Outcomes                      Frequency

                   1                                               6

                   2                                              6

                   3                                              4

                   4                                              5

                   5                                              4

                   6                                              5

                                                              ---- 

                                                              30

                                                              ----                                                                   

What's the use frequency Table ?

• Frequency Table shows that how many times the given outcome occurs.

• It makes easier to find Mean , Mode and Median .

• $\boxed{\bf{Mean = \dfrac{\Sigma x_{i}}{n}}}$

• For Median ,

Arrange the given data in ascending or descending order first.

• No. of observation (If it's Even)
• $\boxed{\sf Median= \frac{1}{2}\Bigg[\Bigg(\frac{n}{2}\Bigg)th \ term + \Bigg(\frac{n}{2}+1\Bigg)th \ term\Bigg] }$

Answer 2

${\huge{\underline{\underline{\sf{Question:}}}}}$

A dice was thrown 30 times and the following outcomes were noted

2,1,2,4,6,1,2,3,6,5,4,4,3,1,1,3,1,1,5,6,6,2,2,3,4,2,5,5,6,4

prepare a frequancy table.

$\huge{\rm{Required \ Answer :)}}$

Let's make Frequency Table

            Outcomes                      Frequency

                   1                                               6

                   2                                              6

                   3                                              4

                   4                                              5

                   5                                              4

                   6                                              5

                                                              ---- 

                                                              30

                                                              ----

${: \longrightarrow}$ Frequency tables are an efficient method of displaying data .

$\huge\mathfrak\blue\star$ The number of cases for each observed score are listed .

$\huge\mathfrak\green\star$ Scores that have 0 cases are included as well .
