Answer :-

  • Mode of the given data is 10.

To find :-

  • The mode of 10, 12, 11, 10, 15, 20, 19, 21, 11, 9 and 10.

Step-by-step explanation :-

We know that :-

  • The number that occurs more times than any other number is the mode of the given data.

  • Here, we have to find the mode of 10, 12, 11, 10, 15, 20, 19, 21, 11, 9 and 10.

Arranging the data in ascending order,

  • 9, 10, 10, 10, 11, 11, 12, 15, 19, 20, 21.

We see that :-

  • Here, 10 occurs more times than any other number and it's frequency is 3.

Hence,

  • Mode of the given data is 10.

The different representatives of measuring central tendency of a statistical data are :-

  1. Mean.
  2. Median.
  3. Mode.

In this question, we learnt what is mode of the data and how to find it. Now let's learn the formula of mean and median!

Formula for mean :-

\sf \dfrac{Sum \: of \: observations}{Number \: of \: observations}

Formula for median when the number of observations is odd :-

 \sf\dfrac{n + 1}{2}  \: th \: observation

Formula for median when the number of observations is even :-

\sf \dfrac{\frac{n}{2} \:  th \: observation +   \left(\frac{n}{2}  + 1 \right) \: th \: observation}{2}
