Is sociology more than statistics?
Sociology is the study of human behavior in a social environment and how social interaction relates to development of mental and physical abilities, as well as future success and failure. Statistics are near irrelevant to sociology because it is a very intuitive field of study. So yes, sociology is much more than statistics.
Why would someone want to assume that your sample data represents a population distrubution?
Most people take samples so that they may make estimates of parameters of interest: mean, variance, etc for the whole population. For such an estimate to have any validity the sample data must be assumed to represent a population distribution. Otherwise any conclusions based on the sample are valid only for the sample: hardly worth the effort!

How do find median of a set of numbers?
you like cross 1 number out on each side until you have one nuber left i think in some cases but im not like 100 percent sure about the two number thing i just know that you cross it out out until you get to the middle
How do you calculate the mean from the median?
The mean is the sum of the sample, divided by the number of samples. The median is the middle number. Good example of this is your grades. You have a d,c,a,b, c,c. Each grade has a number a d is equal to 1 point, c= 2 points, a= 4 points, and a b=3 points. You add these up and divide by the number 7. To find the median write them in order A,b,ccc,d= the median is a C.
What is the advantage of keeping the prism in minimum deviation?
By keeping the prism in minimum deviation position, the RI of the prism can be calculated efficiently.
Any set of the form {a,a,a,a,b,b,b,b,c,c} where a<b<c.
What percentage of people today know who Edgar Allen poe is?
It is close to 0%.
Edgar Allan Poe, the writer, died over 150 t=years ago, so any Edgar Allan Poe who is still alive is a namesake but effectively a nonentity. Therefore, the percentage of people who know who he IS is 0%.
What is the mean, median and mode for 428, 472, 510, 386, 440?
Let's approach this step-by-step:
First, let's order these numbers from least to greatest:
386, 428, 440, 472, 510
Mean:
The mean is the average of all numbers.
Sum: 386 + 428 + 440 + 472 + 510 = 2236
Count: 5
Mean = 2236 ÷ 5 = 447.2
Median:
The median is the middle number when the numbers are in order.
With 5 numbers, the median is the 3rd number.
Median = 440
Mode:
The mode is the number that appears most frequently.
In this set, each number appears only once, so there is no mode.
Therefore:
Mean = 447.2
Median = 440
Mode = No mode (or the set is amodal)
Can you provide a sample of 'Quod Erat Demonstrandum' used in a sentence?

What are some alternative ways of collecting data in a classroom setting?
Telephone survays, Census, Mail-in queationnaire, presentations by citizens, research, door-to-door interveiws
stuff like that?
a question can mean the same as another question and if you want to know the question you asked, try typing in who invented math, that's how i got my answer but it is really really long just to let you know. OK OK have fun researching!!!
