Arithmetic mean is used when:a. In depth study of the variable is neededb. The variable is continuous and additive in naturec. The data are in the interval or ratio scaled. When the distribution is symmetrical2. Median is used when:a. The variable is discreteb

Teach your kid how to use an abacus One of the easiest ways of teaching your child numbers and arithmetic is through the use of an abacus. With the help of an abacus you can teach your child counting‚ addition‚ multiplication‚ subtraction‚ division‚ square roots as well as cube roots. While teaching your child how to use an abacus‚ you will have to

operations in computer arithmetic. The well known ripple carry adder can add two W -bit binary numbers using W binary full adders with latency Wtfa where tfa represents the binary full adder delay 1]. Fast addition can be carried out using various fast adders such as carry-select adder 2] or binary look-ahead adder 3]. These fast adders can also be implemented e ciently using multiplexers only. Another approach to designing much faster

CHAPTER III Research Methodology This chapter discusses the different stages of system development and its design. It also includes project design that discusses the external‚ internal and program design. The next stage of the system development is the project development that presents the different phases that discusses the basic planning to operation. The last two stages are the operation and testing procedures and the evaluation procedure. Project Design Graphical User Interface (G.U.I) Figure
