What are a set of numbers representing some sort of information from the sample or populati?
One example is the "Five Number Summary" consisting of the sample's minimum, lower quartile, median, upper quartile and maximum. Answer Statistics or data set might apply to the set of numbers that represent some sort of information from a sample population. Answer Demographics is the statistical characteristics of a sampled population.
Data is commonly referred to the quantitative attributes of a variable. A data is nothing but a result of something. Through this result, the information is derived. Sometimes we refer to Raw Data which is unprocessed in nature which can mean a collection of numbers or characters that collect information and then convert from quantities to symbols. Sample, in statistics can mean a subset of a population. Population can be huge, so the sample can…
What will happen if the sample you have drawn from the population does not represent the population?
The main advantage is that the sample is representative of the population and the mean of the sample is an unbiased estimate of the population mean. Also, characteristics of other statistics based on the sample are well understood. However, sometimes it may not be possible to gather valid information from a sampling unit and then the sample is no longer random. This can be either because the sampling unit cannot be located or has been…
If the population is of size N, then you allocate the numbers 1 to N to them: one per element of the population. Then generate random numbers in the range 1 - N. The element whose number is thrown up by the generator is in the sample. In the unlikely event that a number is repeated, you ignore the repeat and continue drawing the sample until you have the required correct number in the sample.
Suppose you have a population for which you want to measure some particular attribute. It may not be feasible or sensible to collect the information from each and every member of the population. In that case you can take a subset of members from the population - called a sample - and collect the relevant information for them. Provided that the sample meets certain statistical conditions, the measurements made for the sample will be good…
a census is the procedure of systematically acquiring and recording information about all d members of a given population and a sample is a group from d population a census is more thorough and gives accurate information about a population while being more expensive and comsuming time comsuing rather than a sample
To ensure that the results produced from your sample are fair and true. For example, if you had to pick 10 random numbers between 1 and 6, you could just say numbers that come into your head, but that wouldn't be random because you're choosing the numbers. A more random and fair way would be to roll a die 10 times and use those numbers, because you are in no way picking the numbers.
Ok any math or statistics loving friends out there that can help with this question? The following describes a sample. The information given includes the five number summary, the sample size, and the largest and smallest data values in the tails of the distribution. five number summary is 13,40,50,54,69 and tail end low 13,18,26,28,29 .....tail end high 62,63,63,64,69. Help is greatly appreciated. I used IQR but low numbers are neg and high numbers to high.
