It is organized as a set, and each card has a
Each of one or more types of normal random numbers is
It is composed of a data card written in a certain correlation with one normal random number, and one or more opaque sheets of the same shape and size as the data card, and two or one of the same shape at different positions. A mask card with holes of the same size and two adjacent opaque sides 3A and 3B are configured to have a step higher than a transparent plane portion 3C having a size on which a data card is placed. The card base has a gap 6 large enough to insert a mask card between the upper tier 4 and the lower tier 5, which is a transparent plane slightly larger than the upper tier 4, and is the base of an overhead projector. By combining, operating, and projecting these data cards, mask cards, and card bases as necessary, it is possible to efficiently explain normal random number data and correlation data to many students at once. A teaching tool for explaining normal random number data.
