The aim of the course:
Provide basic principles of experimental design, data collection and evaluation methods before the intensive use of statistical software to get better outputs and prevent misunderstandings during the analysing stage of the research data.. Correlation and regression. χ 2 test, t test, and ANOVA, time series and indices.
Learning OutcomesCTPOTOA
Upon successful completion of the course, the students will be able to :
LO - 1 : gain insight about population-sample, parameter-statistic relationships in fisheries and oceanography.3,12,13,161,3
LO - 2 : construct hypothesis, design scientific experiments, collect and present data.3,12,13,161
LO - 3 : apply measure of central tendency and dispersion for different types of statistical distributions.3,12,13,161,3
LO - 4 : recognise data coming from such distributions as normal, binomial and poisson, sampling (means, difference of means, ratios) and test distributions (z, t, chi-square, F) in order to applye them in their professional field.3,12,13,161
LO - 5 : test hypothesis using Z, Chi-square and variance analysis.3,12,13,161
