Procedure

For this experiment, the independent variable is words and order of appearance of the flash cards. The dependent variable is the ability of each participant to remember the contents of the flash cards. This is determined by asking the participants to write down what they see. The constants (control variables) are the time they are allowed to look at the flash cards and the number of flash cards used.
Two sets of flash cards are used in this experiment. Each set contains 50 cards.
Gather the participants together in a room. Make sure they all have a good visibility of a flashcard. If the group is too big, split the participants into 2 groups.
Hand each participant a data sheet. It will look like this:
The 1st set of flash cards is shown to the participants. They look at each flash card for 5 seconds. After the 50th flash card is shown, they are then given 5 minutes to write down what the have just seen on the flash cards. They are to fill in what they recall, in the first column (Test 1)
The procedure is repeated using the 2nd set of flash cards. This time the participants are required to read out aloud the contents of the flash cards. Again, after the 50th flash card is shown they are then given 5 minutes to write down what they have seen on the flash cards. They are to fill in what they recall in the second column (Test 2)
Collect the data sheets from each participant.

The percentage of improvement in memory retention is calculated as follows:
Total cards observed umber of flash cards x total participant "0 x 10 0 cards.
Total number of cards that were correctly remembered is shown at the bottom of the table.
Percentage of memory retention total number of cards correctly recalled/total number of cards observed) x 100%
