SEMINAR 4

SEMINAR 4 

In seminar 4, held on March 30, we focus on:

• Recoding variables

• Calculations of central tendency and dispersion quantitative variables

• Frequency distribution and confidence interval calculations

• Calculation Graphing of sectors, bar charts and histograms

• Hypothesis test contrast.

A) Chi Square

B) T Student

C) ANOVA test

D) Linear Regression

It is true that this seminar was ahead of schedule with regard to the large group classes because we were a little behind but this served to better understand what soon we were going to give. Therefore mentioning certain terms will suffice because in other related publications appear again and more broadly.

To begin with we have the measures of position, which as we know are the percentiles, deciles and quartiles. 

On the contrary in the measures of centralization we have the median, fashion and average; And finally within the dispersion measures is the variance, standard deviation and path or sampling range.

We also review the inferential statistics, the types of variables... But we can say that the most interesting was the tests of contrast of hypotheses:

• First, CHI QUADRADO, we learned to do it in paper but also in Epi Info to use it in the research work. Observing the results we will accept or not the null hypothesis. We use it in QUALITATIVE-QUALITATIVE.

• T DE STUDENT secondly used in QUALITATIVE-QUANTITATIVE cases; Like the previous case we can also insert in our program this table.

• ANOVA TEST, for more than two variables.

• LINEAL REGRESIONES, where we draw the clouds of points and as in all cases we do also in our program of work. QUANTITATIVE-QUANTITATIVE.

And this was everything we saw in seminar 4, in just two hours gave us time to look over each example but it was not until the large group classes when we finished consolidating the terms and formulas and above all to do more example in Role that ultimately is what serves us in this subject, practice.
