A simple run chart showing data collected over time. The median of the observed data (73) is also shown on the chart. A run chart, also known as a run-sequence plot is a graph that displays observed data in a time sequence. Often, the data displayed represent some aspect of the output or performance of a manufacturing or other business process.
The interface was based on observations of people organizing “data cards” on a table to make graphs to answer specific questions [4] Innovations of TinkerPlots include using a superimposed color gradient [5] to detect covariation in two numeric attributes and a “hat plot,” [6] a reformulated and generalized version of the box plot.
The Principles and Standards for School Mathematics was developed by the NCTM. The NCTM's stated intent was to improve mathematics education. The contents were based on surveys of existing curriculum materials, curricula and policies from many countries, educational research publications, and government agencies such as the U.S. National Science Foundation.

Typically violin plots will include a marker for the median of the data and a box indicating the interquartile range, as in standard box plots. Overlaid on this box plot is a kernel density estimation. Violin plots are available as extensions to a number of software packages, including R through the vioplot library, and Stata through the ...
Data representing each subgroup are taken to be of equal importance if suspected variation among them warrants stratified sampling. If subgroup variances differ significantly and the data needs to be stratified by variance, it is not possible to simultaneously make each subgroup sample size proportional to subgroup size within the total population.
Sixth grade (also 6th grade or grade 6) is the sixth year of formal or compulsory education. Students in sixth grade are usually 12-13 years old. Students in sixth grade are usually 12-13 years old.

One standard deviation above and below the mean of the data set; The 9th percentile and the 91st percentile of the data set; The 2nd percentile and the 98th percentile of the data set; Rarely, box-plot can be plotted without the whiskers. This can be appropriate for sensitive information to avoid whiskers (and outliers) disclosing actual values ...
