Calculating the mean, the standard deviation and the confidence interval of a dataset

1. Calculate the mean and standard deviation for the following dataset: [4.3, 8.4, 5.6, 6.1, 7.5] 2. Calculate the 95% confidence interval around the mean.

Calculating Overall mean and Inferential tests

I. Which measure of central tendency would you use to summarize the data below? 11.2, 13.9, 15.8, 16.6, 28.2, 12.1, 17.3 a. Arithmetic mean b. Mode c. Median d. Weighted mean II. Use the following scenario presented below to answer questions 1 to 2: January rainfall (mm) was recorded at four weather stations along a coastline for several years. The Mean and sample size for each sample are summarized below. Sample 1: n=5 and x'=53.8; Sample 2: n=5 and x'=47.4; Sample 3: n=5 and x'=52.2; Sample 4: n=4 and x'=43.8 1. Calculate the overall mean for the 4 samples. 2. Which inferential test would you use to determine if there is a difference in rainfall between the sample 2 and... click for more

Correlation Analysis & Pearson

I have tried these questions with no luck (see attached file). Is there a quide that you can provide that will help me figure out what test I should be using for certain datasets? Please help!!! thanks.

Correlation

13. Researchers found a correlation of 0.74 between sex (male, female) and education (high school, undergraduate, graduate). What of the following statments is correct? a. more males continue to graduate studies b. more females continue to graduate studies c. it is not appropriate to calculate a correlation coefficient for these data d. the correlation of 0.74 is suspect because we expected a negative relationship Thanks.
