ETHO DATA ANALYSIS HELP
This window enables you to make a variety of simple calculations on single data files or sets of data files. To use these, first load the files you want to analyze using the buttons or menu items, select the appropriate calculation-type radio button, then enter the name of the key or keys you want to analyze.
Menu Tools : Show Interval List: after loading data and performing a particular computation, you can show the list of all the intervals (which underly the reported mean and standard deviation) in a separate window.
Menu Tools : Copy Interval List to Clipboard: after loading data and performing a particular computation, you can copy a list of all the intervals to the clipboard, facilitating import to other programs such as spreadsheets.
Menu Tools : Make Ethogram: use the values for the selected data line to make a simple text ethogram. This will be identical to the ethogram that can be optionally computed at the end of the assay.
Button Show file data: select the file in the table and press "Show Values" button. When the File Data window is showing, clicking on other radio buttons or other files in the File Summary table will change the File Data shown appropriately.
Button Calculate: Select the radio button for the type of calculation you want, type in the key entry to analyze, and press the "Calculate" button. This always acts on all the files in the table and also produces a final line that analyzes all the files together.
Menu File : Show File Overview: after making a calculation, you can return to the file overview (show when files are first loaded) using this menu item.
TIP: from the Main frame, you can create multiple Analysis frames, each of which can analyze data separately, allowing easy comparison.
CALCULATION TYPES
Analyze one key: this function calculates the time interval between each appearance of the indicated keystroke. For each file, the number of intervals, their mean duration, their standard deviation (SD), and their standard error of the mean (SEM) are calculated. The statistical calculations are made using standard definitions.
Relate two keys: this function is very similar to single event periodicity, except that it uses the interval of time between two different events. The two events need not be reliably associated - the calculation is made using the closest pairs of events. Be careful to enter the two keys in the order you want to test them.
Analyze key down: this function calculates features of key down times. It will work only if the files loaded contain key duration (key down time) data. It calculates the number of times the key was down, the total time it was down, and the mean and standard deviation of times it was down.
CALCULATION RESULTS
Analyze one key:
| Interval Number | Mean | St. Dev |
| The number of time intervals between the key strokes. This is one less than the number of keystrokes. | The mean of all the time intervals. | The standard deviation among all the time intervals. |
Relate two keys:
| Interval Number | Mean | St. Dev |
| The number of times key entry 2 follows key entry 1 (before another key entry 1 occurs). Any number of other key entries can intervene without affect. | The mean of all the time intervals. | The standard deviation among all the time intervals. |
Analyze key down:
| Interval Number | Total | Mean | St. Dev |
| The number of times the key was held down. | The total time the key was held down. | The mean of the key down durations. | The standard deviation among key down durations. |
