Why has the issue of meaning moved to the foreground in this so-called postmodern era (20th Century)?© BrainMass Inc. brainmass.com October 25, 2018, 5:16 am ad1c9bdddf
His and thank you for using Brainmass. The discussion below should get you started. This topic can be discussed in many ways but in the social sciences, it has become important primarily because of the discussion below. Don't forget to review your current class materials when putting together your final answer so as to include ideas from there. Good luck with your studies.

On the Importance of Meaning
What is meaning? If we take an existentialist view, we are talking about the worth and value of life. So we ask, over a situation, over an event - what does it mean? We assess it according to what it implies about the social realities we deem it affects. Consider for example the event of the Recession. We ask - what does the recession mean to the American poor, for example. By asking said question, we can come to assess how it affects a particular individual or segment of society, how it affects their social, political and psychic lives. Now, if we take the semiotic view point, meaning pertains to the set of roles and references associated with a particular ...
The solution provides insight and advice on the importance of meaning and why the debate over meaning creation has become very important in the postmodern era. references are listed for further exploration of the topic. A word (.doc) version is also attached.
Importance of Pooled Variance
1. What is pooled variance and why is it important?
2. Explain what interval data is and give an example:
3. Write the formula for a problem that has 2 sample populations greater than 30 and the standard deviations are known and equal:
4. Write the formula for pooled variance.
5. Please analyze the following data:
A school district wants to determine if the girls are equal to boys in test scores. They took a random sample of 22 8th grade girls and 24 8th grade boys. The district looked at recent CAT scores and found the mean score for girls to be xbar1 = 25 and the mean score for boys to be xbar2 = 26. The standard deviation for the girls is s1 = 2.2 and for the boys the standard deviation is s2 = 3.4. Is the school district correct in assuming the girls are equal in performance to boys. They are 95% sure their assumption is correct.
6. Please analyze the following data
A candy company wants to identify whether or not the size of its' candy bars are the same length from one day to another. On day 1 they sample 52 candy bars with an average mean of 5.4 inches and on day 2 they sample 52 bars again with and average mean of 5.6 inches. Both days have sample standard deviations of 3.4. Is the average mean of size different from day 1 to day 2?
7. A sample of 40 observations is selected from one population. The sample mean is 102 and the sample standard deviation is 5. A sample of 50 observations is selected from a second population. The sample mean is 99 and the sample standard deviation is 6. Conduct the following test using 95% level of confidence.
A. Is it a 1 or 2 tail test
B. Compute the statistical calculation
C. What is your decision regarding H1
8. A sample of 65 observations is selected from one population. The sample mean is 2.67 and the sample standard deviation is .75. A sample of 50 observations is selected from a second population. The sample mean is 2.59 and the sample standard deviation is .66. Conduct the following test using 95% level of confidence.
a. Is it a 1 or 2 tail tes
b. Compute the statistical calculation
c. What is your decision regarding H1
9. The Gibbs Baby Food Company wishes to compare the weight gain of infants using their brand versus their competitor's brand. A sample of 40 babies using the Gibbs products revealed a mean weight gain of 7.6 pounds in the first 3 months after birth. The standard deviation of this sample is 2.3 pounds. A sample of 55 babies using the competitors brand revealed a mean increase of 8.8 pounds with a standard deviation of 2.9 pounds. At 95% level of confidence, can we conclude that the babies using the Gibbs product gained LESS weight?
