How many different simple random samples of size 4 can be obtained from a population whose size is 42?
Number of samples = 42C4 = 42*41*40*39/24 = 111930
Is the distribution of sample means always a normal distribution If not why?
It need not be if: the number of samples is small; the elements within each sample, and the samples themselves are not selected independently.
What is sampling and holding time?
sampling time is the number of samples per second taken from a continuous signal to make it discrete and holding time is the time between two samples..
What is statistical data and statistical methods?
Statistical Data: Statistical data science involves the collection, interpretation, and validation of data. It involves a variety of statistical operations performed with some statistical tools without having prior statistical knowledge. There are several software packages for performing statistical data analysis, including SAS (Statistical Analysis System), SPSS (Statistical Package for Social Sciences), etc. There are Different Types of Statistical data : Numerical Data: The data can serve as a measure, such as a person's height, weight, IQ, or blood pressure, or they can serve as a count, such as the number of shares a person owns, a dog's number of teeth, or the number of pages in a book you finish before falling asleep. 2.Categorical data : Categorical data are attributes that can take on numerical values (such as the numbers "1" and "2" indicating male and female, respectively). Ordinary Data : In ordinal data, categorical data are mixed with numerical data. The data fall into categories, but the numbers placed on the categories have meaning. For example, rating a restaurant on a scale from 0 (lowest) to 4 (highest) stars provides ordinal data. Statistical Methods: It is a statistical method that extracts information from research data and provides ways to assess the robustness of research outputs with mathematical formulas, models, and techniques. There are different types of Statistical Methods: Descriptive Methods : A descriptive method involves every step in the analysis and interpretation process, such as the collection of data, the tabulation of data, the measurement of central tendency, the measurement of dispersion, as well as the analysis of time series. This method is also otherwise called descriptive statistics . 2 Analytical methods : This method comprises all those methods which help analyze and compare any two or more variables. These include correlation analysis, regression analysis, attribute association analysis, and the like. This method is also referred to as analytic analysis. Inductive Methods :A generalization procedure consists of all procedures that lead to an estimation of a phenomenon using random observations or partial data, such as interpolation and extrapolation. This methods is also otherwise called inductive statistics. Inferential Methods :In other words, it is a method of drawing conclusions about the characteristics of a population based on samples of data. This method includes theories such as sampling theory, different tests of significance, statistical control, etc. This method is also otherwise called inferential statistics. Applied Methods :These methods are used to solve real-life problems, such as statistical quality control, sampling surveys, linear programming, inventory control, and other procedures.

Explain the importance of ANOVA in the field of Pharmaceutical Science.?
Analysis of variance (ANOVA) is defined as the " Separation of variance ascribable one group of cause from the variance ascribable to another group".The variations may be calculated and their effects estimated by a statistical method known as the ANOVA.USES:# ANOVA is the most powerful statistical tools. # ANOVA is general method of analyzing data from designed experiments. # ANOVA is a powerful process that is useful to analyze the variance between any number of sample. # ANOVA is useful to find significance level between any number of samples and we can analyze whether difference is statistically significant (or) not# This is specially useful to give conclusions for the data obtained in researches. # It keeps the alpha error in a limit. # It is most powerful than t-test as it has no limit in samples that we analyze, T-test is useful to analyze up to only 30 samples. # In the bio equivalence studies the similarities between the samples will be analyzed with ANOVA only. # Pharmacokinetic data also will be evaluated using ANOVA. # Pharmacodynamics (what drugs does to the body) data also will be analyzed with ANOVA only. That means we can analyze our drug is showing significantpharmacological action (or) not.
Is .016 statistically significant in spss?
A number, by itself, cannot be statistically significant. It is necessary to know what the underlying statistical distribution for that number is. That information can be obtained from knowledge of the statistical test being carried out.
How many kids argue with their parents a day?
There is no statistical information for that, though, you can help bring whatever that number is down.
What is statistical landmark?
Number line
What is the formula to getting a average?
Sum of all samples divided by the number of samples.
What is the relationship between levels of confidence and statistical significance?
The connotation 'statistical significance' takes into account the number of samples as well level of confidence in making a conclusion based on these samples. The level of confidence is typically denoted as 1-alpha (1 minus alpha), where alpha is basically the chance that the reported conclusion will incorrect. The most popular level of confidence is 95%, which coincides with a 5% alpha, meaning that when one makes a conclusion based on a particular sample, there is a 5% chance of a false or incorrect conclusion.
Which album includes the highest number of samples?
The Avalanches' album, Since I left You, was made entirely from Samples. Approximately 3,500 samples were used from original vinyls.
How do core samples help geologists?
Geologic core sampling serves a number of important purposes, such as giving scientists information regarding variations of climate. It also provides information about sedimentary composition, and various species.
Which two samples of gas at STP contain the same total number of molecules?
Theoretically, if they have the same volume, all samples will contain the same number of molecules.
What is the characteristic of a normal distribution?
The Normal (or Gaussian) distribution is a symmetrical probability function whose shape is determined by two values: the mean and variance (or standard deviation).According to the law of large numbers, if you take repeated independent samples from any distribution, the means of those samples are distributed approximately normally. The greater the size of each sample, or the greater the number of samples, the more closely the results will match the normal distribution. This characteristic makes the Normal distribution central to statistical theory.
What is the definition of number of samples in statistics?
The number of samples, or sample size, is the number of measurements performed for a particular statistic. For instance, if you were trying to calculate the average price for a bottle of Ardbeg 10 year old Scotch whisky, the number of samples would be the total number of prices you found for Ardbeg at various liquor stores. To continue on with this example, to get the average price, you would then add up all of the prices you measured and then divide that by the number of samples, as described above. It should be obvious that the more stores you visit to measure the price, in this case meaning the higher number of samples you obtain, the more accurate your value for the average price will be.
What is a random number?
* A number generated for or part of a set exhibiting statistical randomness. * A random sequence obtained from a stochastic process. * An algorithmically random sequence in algorithmic information theory. * The output of a random number generator. * The least random number (17), according to the Hacker's Jargon File.
