What does the median tell you about the distribution of a set of data?
the midpoint of the data set
Why you prefer normal distribution over other distributions in statistics?
we prefer normal distribution over other distribution in statistics because most of the data around us is continuous. So, for continuous data normal distribution is used.
What does probalility distribution mean?
In parametric statistical analysis we always have some probability distributions such as Normal, Binomial, Poisson uniform etc.In statistics we always work with data. So Probability distribution means "from which distribution the data are?
What distribution is a sampling distribution referring to?
A sampling distribution refers to the distribution from which data relating to a population follows. Information about the sampling distribution plus other information about the population can be inferred by appropriate analysis of samples taken from a distribution.
What Do You Call A Data Set With Two Modes?
A bimodal distribution.
Does all symmetrical distributions are normal distribution?
It is not necessary that all symetric distribution may be normal.
Where is all the majority of the data when the distribution is skwed right?
on the left and when it is skewed left it is on the right
What type of distribution pattern that occurs when the majority of the data values fall to the left of the mean?
positively skewed
Is a chair symetric?
yes
How do you put the word distribution in a sentence?
1. The typical distribution of data in a bell curve shows that variations occur rarely and the majority of data is clustered around a mean or average. 2. The distribution of funds by the board of directors will be decided based on several factors that affect the organizations needs. 3. After the earthquake, the aid relief was quick to respond with distribution of water, food and medical supplies
Can frequency distribution contain qualitative data?
frequency distribution contain qualitative data
If a great many data values cluster to the left of a data distribution which then tails off to the right the distribution is referred to as?
It is a positively skewed distribution.
How many line of symetric does a fish has?
Many line of
Why cosx is even function?
its graph is symetric x-axises
What artery in the body has no symetric artery on the other side?
aorta
What is a normal data set?
A normal data set is a set of observations from a Gaussian distribution, which is also called the Normal distribution.
What is the mean of the sampling distribution of the sample mean?
Frequently it's impossible or impractical to test the entire universe of data to determine probabilities. So we test a small sub-set of the universal database and we call that the sample. Then using that sub-set of data we calculate its distribution, which is called the sample distribution. Normally we find the sample distribution has a bell shape, which we actually call the "normal distribution." When the data reflect the normal distribution of a sample, we call it the Student's t distribution to distinguish it from the normal distribution of a universe of data. The Student's t distribution is useful because with it and the small number of data we test, we can infer the probability distribution of the entire universal data set with some degree of confidence.
