  • Stemplot
    A visual tool for displaying quantitative data, showing both overall trends and individual values in a dataset.
  • Stem
    The portion of a data value excluding its rightmost digit, used to group similar values in a stemplot.
  • Leaf
    The rightmost digit of a data value, representing individual points within each group in a stemplot.
  • Vertical Line
    A divider separating stems from leaves, forming the structural basis of a stemplot.
  • Ascending Order
    A sequence arrangement where values increase from smallest to largest, essential for constructing a stemplot.
  • Quantitative Data
    Numerical information that can be measured and analyzed, suitable for display in stemplots and histograms.
  • Data Table
    A structured list of values, often used as the starting point for creating a stemplot.
  • Distribution
    The pattern of data spread, trends, and frequencies, which can be visualized using a stemplot.
  • Trend
    A general direction or pattern in data, easily observed in a stemplot alongside individual values.
  • Individual Data Point
    A single value within a dataset, distinctly represented as a leaf in a stemplot.
  • Histogram
    A graphical representation of quantitative data, showing frequency but not individual values.
  • Row
    A horizontal arrangement in a stemplot, pairing a stem with its corresponding leaves.
  • Column
    A vertical arrangement in a stemplot, separating stems from leaves for clarity.
  • Digit
    A single numerical symbol, used to form stems and leaves in a stemplot.
  • Frequency
    The count of data points sharing the same stem, visually indicated by the number of leaves in a stemplot.
