The following list gives the number of pets for each of 11 students two two one two four two four one three one one find the modes of this data set if there is more than one mode write them separated by commas if there is no mode say no mode

To find the modes of this data set, we need to determine the number(s) that appear most frequently. Let's count the frequency of each number:

Number of pets: 1 (frequency: 4)
Number of pets: 2 (frequency: 3)
Number of pets: 3 (frequency: 1)
Number of pets: 4 (frequency: 2)

From this count, we can see that the number 1 appears most frequently (four times). Therefore, the mode of this data set is 1.

Hence, the mode of this data set is 1.

Is there more than one mode

Apologies for the oversight. Upon reviewing the data set, I see that there is more than one mode. The numbers 1 and 2 both appear most frequently, each occurring four times. Therefore, the modes of this data set are 1 and 2.

Hence, the modes of this data set are 1 and 2, separated by a comma.

To find the mode(s) of a data set, we need to determine the value(s) that appear most frequently.

From the given list, we have:
2, 2, 1, 2, 4, 2, 4, 1, 3, 1, 1

Now, let's count the frequency of each value:

1: appears 4 times
2: appears 4 times
3: appears 1 time
4: appears 2 times

Both 1 and 2 appear the most (4 times each). Therefore, the mode(s) for this data set are 1 and 2.

So, the modes are: 1, 2

To find the mode(s) of a dataset, you need to identify the value(s) that occur most frequently. Here's how you can determine the mode(s) for the given data set:

Step 1: Arrange the data in ascending or descending order:
1, 1, 1, 2, 2, 2, 3, 4, 4, 4

Step 2: Count the frequency of each value:
1: 3 times
2: 3 times
3: 1 time
4: 3 times

Step 3: Identify the value(s) with the highest frequency. In this case, the values 1, 2, and 4 all have the highest frequency of 3.

Step 4: Write down the mode(s), separated by commas if there is more than one mode. Therefore, the modes for this data set are 1, 2, and 4 since they occur the most frequently.

Hence, the modes for this data set are 1, 2, and 4.
