A statistical table is a method used to present statistical data by arranging the
numbers systematically and describing some processes.
T score table and Z score table are the two commonly used statistical tables .
4. T S C O R E T A B L E
William Sealy Gosset discovered the T
score table. While discussing statistics and
probability, this table is a member of a
continuous distribution of probability that arises
when the normally distributed population mean
is calculated. This is done when the standard
deviation of the population is unknown, and the
sample size is few.
This shows the description of samples
drawn from a complete population. The T score
table for each size of a sample will be different.
Greater the sample, the more the table shows
the resemblance of a normal distribution .
5. Z S C O R E T A B L E
This table is the standard deviation signed number
by which a data or an observation is above the mean. This is a
table for the values of ϕ, indicating the values of the
cumulative distribution function of the normal distribution.
A positive Z score table denotes the indication of a
data that is above the mean.
A negative Z score table shows the indication of a
data that is below the mean. This table is used in comparing a
sample to a standard normal deviation, even though they
may be defined without normality assumptions .

a picture that shows how sets
of information or variables (= amounts that
can change) are related, usually
by lines or curves; a line drawing made for
mathematical or scientific purposes .
The four most common are
probably line graphs, bar graphs and
histograms, pie charts, and Cartesian graphs
but there are others.
