Question

the data set shows the lengths of snakes in meters.
snake length (m)
1 1 2 2 2
2.5 3 3 3.5 5
check that every data value is shown in your dot plot.
make a dot plot of the data.
snakes
length (m)

Explanation:

Step1: Count the frequency of each data value

• For \(1\): there are \(2\) values.
• For \(2\): there are \(3\) values.
• For \(2.5\): there is \(1\) value.
• For \(3\): there are \(2\) values.
• For \(3.5\): there is \(1\) value.
• For \(5\): there is \(1\) value.

Step2: Plot the dots on the number line

• At \(1\) on the length axis, place \(2\) dots.
• At \(2\) on the length axis, place \(3\) dots.
• At \(2.5\) on the length axis, place \(1\) dot.
• At \(3\) on the length axis, place \(2\) dots.
• At \(3.5\) on the length axis, place \(1\) dot.
• At \(5\) on the length axis, place \(1\) dot.

Answer:

The dot - plot is made as per the above steps with the correct number of dots at each data value position (e.g., two dots at \(1\), three dots at \(2\), one dot at \(2.5\), two dots at \(3\), one dot at \(3.5\) and one dot at \(5\)).
