StatisticsCalc Help

The Calcinator  StatisticsCalc is a powerful tool for analyzing datasets of up to 1000 samples. There are four memory areas DS1-DS4 that can be used to store datasets.


Data Entry

Select a dataset DS1-DS4 as a repository for the samples. Use the numeric keypad to enter sample data one at a time. Use the ↲ button to enter a value into the selected dataset. Each sample is displayed in the sliding window and is associated with a sample index number and a green ✔ to the right.

The green ✔ denotes an active sample. Clicking on the green ✔ will change it to a red ✖ which denotes a deselected sample. Any sample that has a red ✖ will be excluded from report calculations. This is handy for testing the effect of outliers on the dataset statistics. The All→✔ check in the sliding data display will select or deselect all samples in the dataset. The Clr✖ button will pemanently delete any samples marked with a red ✖.


Data Import/Export

The Data button will bring up the Data Import/Export page. This page allows the user to export datasets or import lists of data via cut/paste from other sources. Data is organized by sample and delimiter. There are five possible data delimiters:

  • [Line] - each data sample is separated by a new line
  • [Space] - each data sample is separated by a blank space
  • , - each data sample is separated by comma
  • ; - each data sample is separated by a semicolon
  • : - each data sample is separated by a colon

To import data, select a dataset DS1-DS4 then press the data button. Cut and paste a set of data from another source such as a spreadsheet into the data window. Select the appropriate delimiter and press the Import key. If the import was successful, the N=x indicator in the status window will display the correct sample size. Then press Save to save the data to the selected dataset. This operation will overwrite any previous saved data in that dataset!


Reports

After data is entered, pressing the Report button will generate a statistics report on the selected dataset. This report consists of the common statistical measures used for single datasets of unordered numeric data. At the bottom of the page is a set of buttons used to correlate one dataset to another using conventional linear regression techniques. Select a different dataset to compare with the primary dataset and press the Corr button to generate a Correlation report. Correlations are only valid on paired data between two datasets. Both must be the same sample size or the report may generate an error.


Shared Memory M1-M6

The MR (Memory Recall) button is used to recall values from six memory locations M1-M6 that were saved from other Calcinator apps. Contents of the selected memory location is displayed in the status window at the bottom of the page. The StatisticsCalc only recalls from memory to be used as sample elements. DS1-DS4 are used to store datasets. Like memory locations, Datasets are saved to cookies that retain data for later use. This means that if cookies are deleted, so are your datasets.
