pieces together. 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 1.

Introduction Sternberg (1999) suggested that “Memory is the means by which we draw on our past experiences in order to use this information in the present” (Eysenck & Keane 2005‚ p. 207). According to psychological theorists the term memory covers three important aspects of information processing which are known

measurement. OTHER CONCEPTS IN SCALING AND MEASUREMENT Description: It means unique labels or descriptions used to designate each value. Such as‚ 1 = Strongly disagree. Order: It means relative sizes of the descriptors. 4 = Agree but 5 = strongly agree Distance: It means absolute differences between the scale descriptors are known or may be expressed in units. Such as‚ 5 is 1 unit more than 4 in the scale. Origin: This means the scale has a unique or fixed beginning or true zero point. EXAMPLES

If for example n = 100 we would need 4750 parameters‚ and if n = 1000 we would need 501‚ 500 parameters! At best we could try to estimate these‚ but how? In fact‚ it is easy to see
