Values vs. variables A variable is any measured characteristic or attribute that differs for different subjects. Variables are things that we measure, control, or manipulate in research. Simply something that varies. The variable is the name of the scale along which the values lie. Given several values, what is the name of the variable along which the values lie? 1. 16 ounces, 32 ounces, 1 pound: 2. One month old, 2 years old, 10 years old, 20 years old 3....

Assume that we have a finite population of 5 elements on which we measured a random variable X. Below are the observations of Xover the population: {0,1,2,3,4). Assume that we want to select a random sample of size 3 form this population. Let S be the sample variance. a. Find the distribution of S2 b. Calculate E(S) c. Calculate Var(s)

we did a lab where we measured the pH of different diluted solutions of HCL and Acetic acid. Then we compared these data with theoretical values that we calculated. The measured and calculated values varied a little bit. We also measured the ph of NaCl, which theoretically should be neutral, but its ph was 5.23. What can be some sources of error?
