1.7 DEFINITION OF TERMS USED IN THE PROJECT
Stratified
Sampling: - It cab be explain as random sample, is one obtained by
separately the population elements or units into non-overlapping group
culled strata and then selecting a simple random sample from each
stratum.
Multiple Correlations: - This is the degree of
relationship that exists between three or more variable X1 X2
X3represent the variables under consideration. Then we can let X11 X12
X13 ……. Represent or denote the values assumed by the variable X1 and
X21, X22, X23 denote the value assumed by the variables X2 and so on.
With this notation a sum as X21 + X22 + X23 +, +, + , + X2N could be
written ∑X2.
Analysis of Variance (AWOVA): - Another important
distribution is the F-distribution, named in honour of R.A Fisher, who
first developed and describe it. The random variable F is also a test
statistic and is define as the ratio if unbiased estimates of two
population variances i.e. F = S / S . The F-distribution is used for
inferences of this kind. The procedure of testing for the equality of
three or more means is provided by statistical techniques which
represent an important application of F-distribution or Analysis of
variance.
Measure of Central Tendency: - A set of data has a number
of important features. If the data set consists of number we are not
often interested in two characteristics of the data. The first is a
number that is considered most representative of the set e.g. mean,
median and mode.
Measure of Dispersion: - These measures serve to
locate the “center†of the distribution but they do not reveal how the
items are spread out or scattered on each side of the centre. This later
characteristic of a distribution is commonly referred to as the
dispersion e.g. variance, standard deviation.

ABSRACT - [ Total Page(s): 1 ]This project has the aim of studying the uses of contraception drug among female student of faculty of science in Osun State Polytechnic, Iree. The study employed the use of statistical method like measure of central tendency, stratified sampling techniques, analysis of variance (ANOVA), co-efficiencies of correlations. The result of the analysis shows that there is relationship between the student and their attitude towards contraceptives. ... Continue reading---
