1/13
  • Stemplot
    A visual tool that displays both the distribution and individual values of quantitative data using stems and leaves.
  • Histogram
    A graphical representation of quantitative data showing frequency distribution but not individual data values.
  • Quantitative Data
    Numerical information that can be measured or counted, often used for statistical analysis.
  • Data Table
    An organized arrangement of values, typically used as the starting point for constructing visual data displays.
  • Stem
    All digits of a number except the rightmost one, used to group data points in a stemplot.
  • Leaf
    The rightmost digit of a number, representing individual data points in a stemplot.
  • Vertical Line
    A drawn separator in a stemplot that divides stems on the left from leaves on the right.
  • Ascending Order
    A sequence where values increase from smallest to largest, essential for organizing data before plotting.
  • Data Distribution
    The overall pattern or spread of values within a dataset, often visualized in plots.
  • Trend
    A general direction or pattern observed in data, such as clustering or gaps, highlighted by visual displays.
  • Data Point
    An individual value or observation within a dataset, each represented as a leaf in a stemplot.
  • Practice
    The process of applying learned steps to construct or interpret stemplots for better understanding.
  • Example
    A specific dataset or scenario used to illustrate the construction and interpretation of a stemplot.
