the three arrows at upper left point to the time increment for making a move, and indicators of whether it is black's move or white's. Press on them to set the increment, black's time, or white's time. Press go to start and stop: current player's time is displayed in larger numbers and other player's time in smaller. Press the scroll up or down key to switch players.
Press fh / mh to tally one member of the larger groups f and m ("female heads" in the class, or "female hands" that have been raised). Whenever you have a full tally of females and males, press >base to enter that into the baseline ratio and; from now on the number of speeches is compared to this ratio for statistical significance (if the class has 30 women and only 3 men and the men speak exactly half the time, they are still taking up more than their share).
Press f / m when a male or female starts to speak. Press end when the last person ends their speech.
Press dump to get a readout of all the data collected for this group so far: on top is the female head(or hand) count; then male head(or hand); then the number of times a female has spoken with (4 points after the decimal point) the total number of minutes these speeches took; then the male speeches with total speech length; then the percentage of women in the larger group (i.e. the base).
Press dis? to search for discrimination: outputs the average length of a female speech (in minutes); same for a male speech; the total number of speeches with the total length of speech/1000 after the decimal point; the extra times a woman has spoken vs. what would be expected; and the Z-score (number of standard deviations from the mean) that that represents. Then press Z>P to turn the z-score into a P-score. If this is less than 2.5% or greater than 97.5%, there is a statististically significant process of discrimination going on here.
Press load to (possibly) save the current counts and clear the counts or load them from a slot. There are 6 slots.
Note that this counting is expressed in terms of females, males, and a classroom, but the statistics are valid for any two groups in any setting.
To roll a 5-sided die, press 5 then Dx. To roll 3 20 sided dice and add them, press 3, enter, 20, yDx.
Da, Db, and nDm are default dice. To set them to be D6,D20, and 3D6 press the > twice. To roll them, simply press the appropriate one. To set one to another value (for instance, Da to be D8): press 10,>,Da. (remember to enter 2 numbers for nDm). To display what kind of die (for instance) Db is, press 0,>,Db.
5*dn rolls 5 copies of one of the default dice and shows all 5 totals. You can also set it to reroll+add 6 or higher, as in Vampire die pools (the default). To set how this works, press the number to reroll on, then >, then 5*Dn.
dp-- decrements the die pool and displays the number of dice currently in it. Press 8,>,dp-- to put 8 dice in the die pool. Press max> to reset the die pool to its most recent maximum.
hp keeps track of hitpoints. Hit >,hp to set hit points, hp to show them. Press -hp to decrement the hitpoints by the large number shown and then display them(negative numbers increment).
