To make comparison and statistical analysis easier, numerical data is systematically and logically represented in tabulations as rows and columns. Grouping relevant data together makes comparison easier and aids in statistical analysis and interpretation.
To put it another way, tabulation is the process of organizing data and presenting it in a tabular format. Depending on the type of categorization, it might be double, complicated, or simple.
The below table yields that
The total number of students is 315
The fraction of girls in the class is 150/315 = 0.4762
So, the percentage of girls in the class is 47.62%
Hence the percentage of boys in the class is (100-47.62)% = 52.38%
The fraction of students that love Math is 115/315 = 0.365
So, the percentage of students that love Math is 36.5%
The fraction of students that love Reading is 70/315 = 0.22
So, the percentage of students that love Reading is 22%
The fraction of students that love Science is 130/315 = 0.4127
So, the percentage of students that love Science is 41.27%

Answer:
The distance of the object from the base of cliff is 18.24 meters
Step-by-step explanation:
Given as :
The height of the vertical cliff = h = 50 meters
The distance of the object from the base of cliff = x meters
Let The angle of depression of object that level with cliff base = Ф = 70°
<u>Now, from figure</u>
Tan angle =
I.e TanФ =
Or, TanФ =
Or, Tan 70° =
Or, 2.74 =
∴ x =
I,e x = 18.24 meters
So, The distance of the object from the base of cliff = x = 18.24 meters
Hence,The distance of the object from the base of cliff is 18.24 meters Answer
