2 New Keyboard Functionality View all shortcut keys from the help menu Figure 1: Keyboard Shortcuts Interact with the return key similar to how Google Sheets operates. Shortcut keys for all top level menu items have been introduced. For PC users : Ctrl + Alt + keyval_ For Mac users : Option + Shift + keyval_ Interact with the fields in the Build dialog box using the space bar to make selections after tabbing through. Figure 2 : "Build" Dialog box Access all buttons on result windows using keyboard tab functionality. Switch between open dialog windows by selecting the window you want to access through the StatCrunch > Results menu option Select multiple cells by holding down the Shift key and using the arrow keys to navigate in the required direction. Selected area will be highlighted. Figure 3: Cells selected by using the keyboard April 2018 Release Notes Page 2

3 Measures to Aid Interactivity within the Application Row Headers Hovering over a row header brings up an arrow. On click, the following options will be made available: Select row Insert a row above Insert a row below Delete row Clear row Figure 4 : Manage Rows Column Headers Hovering over a column header brings up an arrow for the respective column. On click, the respective tool option will be displayed. Figure 5: Manage Columns Insert 1 column to the left Inserts a blank column with the column title Insert 1 to the left of the selected column Insert 1 column to the right Inserts a blank column with the column title Insert 1 to the right of the selected column Delete column Deletes the column. April 2018 Release Notes Page 3

4 Clear column Clears all data within the column, including the column title. Move column Moves the column to the destination specified through the pop-up. Figure 6 : Move Column Rename column Renames the column to the name specified through the pop-up. Figure 7: Rename columns Resize column Resizes the column based on the criteria provided in the pop-up. Figure 8: Resize Columns Sort Table in Ascending order Sorts the table rows in ascending order based on the selected column Sort Table in Descending order Sorts the table rows in descending order based on the selected column April 2018 Release Notes Page 4

5 New Survey Features Surveys can now accompany an additional question type and include images. Users can also manage which question summaries they would like to display on the respondent result summary view. Add Multi-Selection Questions Add a multi-choice question and allow respondents to select multiple options from the list of items. View summary results for the multi-selected options in a graphical format. Capture and analyze the results in the StatCrunch App. Figure 9 : Select the checkbox to allow multiple selection for this question Figure 10 : Multi selection view on survey Figure 11 : Analyze multi selection data on the application April 2018 Release Notes Page 5

6 Add Images to Questions Add an optional image when setting up a question. Remove or replace the image associated with a question. Viewers will see the images displayed within the survey form when responding to questions.

8 Changes to Survey Settings Default setting for all questions All questions on a survey are now required to be responded to by default. Validations are available and prompts will be displayed if respondents attempt to submit a survey without responding to all questions. Figure 15 : Validation prompts April 2018 Release Notes Page 8

9 Excluding a question from summary view The option to exclude questions from the summary view has been introduced. Simply select the check mark option available when setting up the question to indicate that it should not be displayed in the response summary for respondents. Figure 16: Select to exclude question from summary results for respondents April 2018 Release Notes Page 9

10 Validation for minimum number of items Survey creators are now required to enter at least two items when setting up multi-choice and multi-selection questions, so that respondents have more than one item to choose from for a particular question. Figure 17: Question set up validation April 2018 Release Notes Page 10

11 Time Series Analysis A new Time Series menu is now available in StatCrunch which covers Trend Analysis, Moving Average, both single and double Exponential Smoothing, Holt - Winters Smoothing, both Autocorrelation and Partial Autocorrelation, Differences, and Lag. April 2018 Release Notes Page 11

12 Trend Analysis Will fit a linear, quadratic, or exponential model to time series data. Ability to forecast values using the specified model. The statistical output includes the least squares model estimates along with MAPE, MAD, and MSD accuracy measures. By default the Time series plot is included in the output. Other option graphs available are the Residual index plot, the Histogram of residuals, and the QQ plot of residuals. April 2018 Release Notes Page 12

13 Moving Average (Weighted and Non-Weighted) Choose between a standard Moving Average or the Weighted Moving Average smoothing. Ability to forecast values using the specified model. The statistical output includes the MAPE, MAD, and MSD accuracy measures. By default the Time series plot is included in the output. Other option graphs available are the Residual index plot, the Histogram of residuals, and the QQ plot of residuals. April 2018 Release Notes Page 13

14 Exponential Smoothing Choose between a Single Exponential Smoothing (with only one weight in model) or Double Exponential Smoothing (two weights in model). Either enter the desired model weights or allow StatCrunch to algorithmically search for the optimal weights that give the lowest sum of squares error. Ability to forecast values using the specified model. The statistical output includes the MAPE, MAD, and MSD accuracy measures. By default the Time series plot is included in the output. Other option graphs available are the Residual index plot, the Histogram of residuals, and the QQ plot of residuals. April 2018 Release Notes Page 14

15 Holt Winters Smoothing Holt - Winters is also known as Triple Exponential Smoothing with an additional seasonal component to the model. The Multiplicative model type will have the seasonal component multiplied onto the model, whereas the Additive model type has the seasonal component added onto the model. Either enter the desired model weights or allow StatCrunch to algorithmically search for the optimal weights that give the lowest sum of squares error. The Transformation will transform the selected column of data before the model calculations begin. Included is the ability to un-transform the observed values and fits for the graphical results. Ability to forecast values using the specified model. The statistical output includes the MAPE, MAD, and MSD accuracy measures. By default the Time series plot is included in the output. Other option graphs available are the Residual index plot, the Histogram of residuals, and the QQ plot of residuals. April 2018 Release Notes Page 15

16 Autocorrelation and Partial Autocorrelation Both Autocorrelation and Partial Autocorrelation graphs are included for this new feature. Graphical results include the 95% significance limits. April 2018 Release Notes Page 16

17 Calculate Differences between Columns Allows for the creation of a new column of data which calculates the differences between values in an existing column based on the specified lags. For example, a lag of 1 will have the 1st value from the original data column in the second row of the new data column. April 2018 Release Notes Page 17

18 Lag Allows for the creation of a new column of data that is the lagged version of an existing column of data. For example, a lag of 2 will calculate row 3- row 1, row 4 - row 2, row 5 - row 3, etc. April 2018 Release Notes Page 18
