A distribution table would be primarily used in the field of statistics and probability. Collecting and interpreting data is much easier when compiled in this format.

What is the difference between standard normal distribution table and the t distribution table?
standard normal is for a lot of data, a t distribution is more appropriate for smaller samples, extrapolating to a larger set.
Can the unit normal table be used for any normal distribution?
Yes, if you mean normal with a mean other than 0 and/or standard error other than 1. If m is the mean and s the standard error, then transform the original data, y, using: z = (y - m)/s z will have the N(0,1) distribution!!!!!!!
What is simple frequency distribution table?
The frequency distribution table lists all the possible events and how many times (frequency) they occurred.
How much is 84 percentile equals mean plus 1 standard deviation or mean plus 1.4 standard deviation. Can you give me reference also please?
The cumulative probability up to the mean plus 1 standard deviation for a Normal distribution - not any distribution - is 84%. The reference is any table (or on-line version) of z-scores for the standard normal distribution.
If a sample of n 15 scores has been organized in a grouped frequency distribution table it is possible to obtain a list of all 15 scores from the table?
true
What is table algebra?
Table algebra is the branch of mathematics like geometry and others.

standard normal is for a lot of data, a t distribution is more appropriate for smaller samples, extrapolating to a larger set.
What is the principle behind the Z score table?
The z-score table is the cumulative distribution for the Standard Normal Distribution. In real life very many random variables can be modelled, at least approximately, by the Normal (or Gaussian) distribution. It will have its own mean and variance but the Z transform converts it into a standard Normal distribution (mean = 0, variance = 1). The Z-distribution is then used to make statistical inferences about the data. However, there is no simple analytical method to calculate the values of the distribution function. So, it has been done and tabulated for easy reference.
Why does a researcher want to go from a normal distribution to a standard normal distributio?
A normal distribution simply enables you to convert your values, which are in some measurement unit, to normal deviates. Normal deviates (i.e. z-scores) allow you to use the table of normal values to compute probabilities under the normal curve.
In a normal distribution which statement best describes the relationship between mean median and mode?
[object Object]
What value of Z from the standard normal distribution table has an area to the left probability equal to 0.0764?
-1.43 (approx)
When do you use a z - table compared with when you use a t - table?
For statistical tests based on (Student's) t-distribution you use the t-table. This is appropriate for small sample sizes - up to around 30. For larger samples (or degrees of freedom), the t-distribution becomes very close to the Standard Normal distribution so you use the z-tables.
Are you provided the normal distribution chart on the SOA Society of Actuearies Exam 1 -- Exam Probability?
Yes, they provide the normal distribution z table on the P1 exam, at least on the computer exam. I'm not sure about the paper and pencil exam.
What is a frequency table in mathematics?
Mathematics frequency table is a graph that is used for data value. This makes it easier for things to be graded.
Can the unit normal table be used for any normal distribution?
Yes, if you mean normal with a mean other than 0 and/or standard error other than 1. If m is the mean and s the standard error, then transform the original data, y, using: z = (y - m)/s z will have the N(0,1) distribution!!!!!!!

What table is used to group data into intervals?
Frequency Distribution Table
