Assignment $1-$ SACR $3080,$ Winter $2024$

In this assignment you are asked:

to obtain basic descriptive statistics and plots $($histograms$,$

barplots and$/$or boxplots, as appropriate$),$ for four variables,

described below.

to obtain a boxplot for 'feelnerv' by 'hometown'.

to standardize the ordered variables. $($Obviously$,$ this would

make no sense for a nominal variable.$)$

The syntax that produced your results must be handed in$.$ You

do not have to$,$ and should not, hand in your output. The

syntax you hand in should be clean, that is$,$ it should contain

no extra commands, and it should contain no errors.

$(40$ points$)$

to explain, for each variable, its level of measurement.

Please treat them in this order: age, hometown, mixedsex and

feelnerv. Note that guessing right will get you no marks. The

points will be given for your explanations of why you have

chosen specific levels. $(12$ points$)$

to describe the central tendency, dispersion and shape of each

variable. Your description should include the numeric value

of appropriate measures, with whatever else you need for

a given variable. You should report everything for a specific

variable at once, one variable at a time, in the order: age,

hometown, mixedsex, and feelnerv.

As appropriate, you can and should use more than one statistic

to describe central tendency and dispersion. You can describe

the shape of the distributions verbally. $(16$ points$)$

to explain the advantages and disadvantages of the measures

of central tendency and of dispersion used. You only need to

explain each measure once, however many times you have

used it$.(18$ points$)$

to explain the meaning of one single$-$variable boxplot you have

requested, and the meaning of the two$-$variable boxplot.

$(10$ points$)$

to explain, for a standardized variable, what is

meant by scores of $-\mathrm{.}57,0\mathrm{.}0,$ and $2\mathrm{.}10.(6$ points$)$
