25
Dot Plot
a graph that uses dots to show the frequency counts of a group of data. Dot plots are used for small sets of quantitative data. You can easily identify the mode, the shape or skew of the graph, and potential outliers on a dot plot.
26
Meniscus

27
Grams (g)
the base metric unit of mass
28
Categorical Data
data recorded as categories/groups
29
Margin of Error
deviation or variation of a value from the correct or expected value to allow for error in equipment or calculations
30
Invariance
Consistency of the size or magnitude of a value regardless of a change in units.
31
Pie Chart
a graph in which a circle is divided into sectors that each represent a proportion of the whole. Pie charts are helpful when displaying the relative distribution of categories.
32
Estimate (verb)
To approximate a value by comparing to a known value.
33
Measurable Attribute
Characteristic of an object that can be assigned a size or magnitude.
34
