Considering each observation xi as an outcome from a random variable Xi ‚ we have that functions g(x1 ; x2 ; :::; xn ) are draws from the random variable Pn g(X1 ; X2 ; :::; Xn ): For 120a the function we are interested in is the sample mean — g(x1 ; x2 ; :::; xn ) = n1 i=1 xi : In this chapter we work with this function for distributions with many random variables. 1 From the Text Question

Effective Teaching Methods Used by Our Prophet Mohammad S.A.W Our Prophet Mohammad S.A.W used several ways of teaching‚ which we must follow to become a highly effective teacher. Few of the methods are discussed below: Method of questioning and dialogue To gain the attention and test the knowledge of the people and to kindle their curiosity‚ the Prophet used to pose them with questions and answer it later. Ibn Omer reported that once Prophet asked his companions

- both are used by simply pushing the probe into the soil and reading themeter. Errors can be made when measuring abiotic factors when the soil moisture or pH meter probes are not cleaned between readings. As always the results can be made more reliable by taking many samples. Here are some examples: Daisies The more light available‚ the more daisy plants will be present.0 This is because daisies need light energy from the sun to make their own food (photosynthesise). Sampling plants 1.

NOT FOR COMMERCIAL DISTRIBUTION 3 Simple Random Sampling 3.1 INTRODUCTION Everyone mentions simple random sampling‚ but few use this method for population-based surveys. Rapid surveys are no exception‚ since they too use a more complex sampling scheme. So why should we be concerned with simple random sampling? The main reason is to learn the theory of sampling. Simple random sampling is the basic selection process of sampling and is easiest to

In small populations such sampling is typically done "without replacement"‚ i.e.‚ one deliberately avoids choosing any member of the population more than once. Although simple random sampling can be conducted with replacement instead‚ this is less common and would normally be described more fully as simple random sampling with replacement. Conceptually‚ simple random sampling is the simplest of the probability sampling techniques. It requires a complete sampling frame‚ which may not be available

SAMPLING TECHINIQUE PROBABILITY SAMPLING Having chosen a suitable sampling frame and established the actual sample size required‚ you need to select the most appropriate sampling technique to obtain a representative sample. The basic principle of probability sampling is that elements are randomly selected in a population. This ensures that bias is avoided in the identification of the elements. It is an efficient method of selecting elements which may have varied characteristics‚ as the process
