Line Plots with Fractional Measurements

The measurement that has the most Xs above it is the most frequent.

We looked at the shortest and tallest measurements and used these to decide where to begin and end the number line.

No, I can just work my way through a list of values, marking an X for each data point on the line plot above the appropriate measure.

I can see the range of values in the data set. I can calculate the difference between the greatest amount and the least amount.

Line plots allow you to ‘see’ trends and to easily see which measurement occurs most frequently.

No, I need to include all measurements in the range, since seeing the gaps helps me understand the data better.

The data values help determine whether to divide wholes in halves, fourths, or eights. I need a tick mark for each value in the data set.

The total number of Xs is how many data values there are in the data set.

Subtract the smaller value from the larger value. Or count up from the smaller to the larger value.

I can multiply 3×1[ggfrac]1/2[/ggfrac], or I can add 1[ggfrac]1/2[/ggfrac] + 1[ggfrac]1/2[/ggfrac] + 1[ggfrac]1/2[/ggfrac].
