2. 11
3. 17
4. 19

Answer 1

Answer:

the middle most number is 17

mode = 17

Answer 2

Given:

We have gien a set of data which is 17, 19, 18, 17, 18, 19, 11, 17, 16, 19, 15,

15, 15, 17, 13, 11.

To Find:

We have to find the mode of given data?

Step-by-step explanation:

• We have given the terms of any data is 17, 19, 18, 17, 18, 19, 11, 17, 16, 19, 15,15, 15, 17, 13, 11.
• Mode:
• The mode of any set of data is defined as the number which has maximum no. of frequency.
• Frequency: The frequency of any number is the number of time that number occur in the set of data.
• From the given data we have a frequency of 17 is 4.
• The frequency of number 19 is 3.
• The frequency of number 18 is 2.
• The frequency of number 11 is 2.
• The frequency of number 16 is 1.
• The frequency of number 15 is 3.
• The frequency of number 13 is 1.
• Hence the number 17 has the maximum frequency which is 4.

Thus, the mode of data is 17.
