14. Sampling Error 4.54.03.53.0 150 100 50 0 Self esteem Frequency The population has a mean of 3.75......and a standard error of.25. This means About 64% of cases fall between 3.5 - 4.0. About 95% of cases fall between 3.25 - 4.25. about 99% of cases fall between 3.0 - 4.5

15. Sampling Error The standard error is called the sampling error. 4.54.03.53.0 150 100 50 0 The sample of 1000 has a mean of 3.74 and a standard error of.0074. Self-esteem Frequency

16. Sampling Error The sampling error shows that the odds are.95 that the population mean is 3.74 + 2(.0074). 4.54.03.53.0 150 100 50 0 Self-esteem Frequency The sample of 1000 has a mean of 3.74 and a standard error of.0074.

17. Sampling Error 4.54.03.53.0 150 100 50 0 Self-esteem Frequency The sampling error shows that the odds are.95 that the population mean is 3.74 + 2(.0074). The sample of 1000 has a mean of 3.74 and a standard error of.0074. Confidence level

18. Sampling Error 4.54.03.53.0 150 100 50 0 Self-esteem Frequency The sampling error shows that the odds are.95 that the population mean is 3.74 + 2(.0074). The sample of 1000 has a mean of 3.74 and a standard error of.0074. Confidence interval
