A die is rolle 16 times and the number that ad for each roll was recorded.
Number on die for each roll
5 2 2 6
1 4 6 1
1 3 5 2
2 3 4 4
If this data were to be displayed using a dot plot, what numbers would be displayed along the horizontal number line?
Which numbers along the horizontal number line would have the same amount of dot abve them?
The numbers 1 - 6 on horizontal
There are 2 fives
There are 2 sixes
There are 2 threes
To create a dot plot, we will display each unique number along the horizontal number line and represent each occurrence of that number with a dot above it.
First, let's examine the numbers given:
5, 2, 2, 6,
1, 4, 6, 1,
1, 3, 5, 2,
2, 3, 4, 4.
The unique numbers in this data set are 1, 2, 3, 4, 5, and 6. These numbers will be displayed along the horizontal number line.
Next, we count the number of occurrences for each number:
Number 1 occurs 3 times.
Number 2 occurs 3 times.
Number 3 occurs 2 times.
Number 4 occurs 3 times.
Number 5 occurs 2 times.
Number 6 occurs 2 times.
To display the dot plot, we mark each number along the horizontal number line and place the corresponding number of dots above each number.
The dot plot would look like this:
Number line:
1
2
3
4
5
6
Dot representation:
1: • • •
2: • •
3: • •
4: • • •
5: • •
6: • •
Looking at the dot plot, we can see that the numbers 1, 2, and 4 all have 3 dots above them, indicating they occurred 3 times. Therefore, these numbers would have the same amount of dots above them.
