Earl Babbie exercise using the MEAN and RANGE using BIVARIATE TABLES

Using the MEAN & RANGE to describe the distribution of responses to the question, "How often have you used the library as a place to study.." FOR ALL RESPONDENTS.

Analysis. We assume that there are 4 months and 16 weeks in one semester.

There are FOUR groups of RESPONDENTS: graduate students; undergraduate students; males and females. For each of their distribution of responses, the mean and range are

a) graduate students.

There are 243+87+24+15=369 graduate students in total. So,

Mean=

Range=maximum-minimum=16-0=16

b) undergraduate students.

There are 105+89+69+92=355 undergraduate students in total. So,

Mean=

Range= maximum-minimum=16-0=16.

c) males.

There are 58+33+21+28=140 males in total. So,

Mean=

Range= maximum-minimum=16-0=16.

d) females.

There are 290+140+72+77=579 females in total. So,

Mean=

Range= maximum-minimum=16-0=16.

Next CONSTRUCT 2 BIVARATE TABLES. Each should be TITLED, PERCENTAGE, & INCLUDE THE NUMBER OF CASES ON WHICH THE PERCENTAGES ARE ...

- "Your solution, looks excellent. I recognize things from previous chapters. I have seen the standard deviation formula you used to get 5.154. I do understand the Central Limit Theorem needs the sample size (n) to be greater than 30, we have 100. I do understand the sample mean(s) of the population will follow a normal distribution, and that CLT states the sample mean of population is the population (mean), we have 143.74. But when and WHY do we use the standard deviation formula where you got 5.154. WHEN & Why use standard deviation of the sample mean. I don't understand, why don't we simply use the "100" I understand that standard deviation is the square root of variance. I do understand that the variance is the square of the differences of each sample data value minus the mean. But somehow, why not use 100, why use standard deviation of sample mean? Please help explain."
