DeltaCE 1.9: statistics.

more → Statistics:

  • Your data in two columns, x and y: type values in place (enter or an arrow keeps one, del deletes; edit inserts, deletes, sorts by x, clears). They are the lists L1 and L2, so mean(L1) works in the console too.
  • x stats / y stats: a box plot and n, mean, sum, sample and population standard deviation, min, Q1, median, Q3, max (quartiles the TI's way).
  • fit: linear, quadratic, cubic (exact when the data are: y = 33/7 x + 324/7), exponential, power, logarithmic, with r and r², a predicted y, and graph: the points with the curve, traced point by point. plot: the points alone.
  • The statistics commands (mean, median, stdDev, linear_regression, ...) are in the command search; median is exact.

Fixed: leaving a screen with clear could make the next calculations fail; the more menu covered the status bar.

Install: from the DeltaCE page in Chrome or Edge, or send DeltaCE.b84 with TI Connect CE. For the TI-84 Plus CE and TI-83 Premium CE on OS 5.3 to 5.8.4; installing erases the calculator's apps and archived files.
