This table shows the number of times each value of ESTRATO

occurred, as well as percentages and cumulative statistics. For

example, in 4 rows of the data file ESTRATO equaled 1. This

represents 8,0% of the 50 values in the file. The rightmost two

columns give cumulative counts and percentages from the top of the

table down.

Data variable: # PERSONAS POR HOGAR

50 values ranging from 3,0 to 7,0

The StatAdvisor

---------------

This procedure is designed to summarize a single sample of data.

It will calculate various statistics and graphs. Also included in the

procedure are confidence intervals and hypothesis tests. Use the

Tabular Options and Graphical Options buttons on the analysis toolbar

to access these different procedures.

The StatAdvisor

---------------

This table shows summary statistics for # PERSONAS POR HOGAR. It

includes measures of central tendency, measures of variability, and

measures of shape. Of particular interest here are the standardized

skewness and standardized kurtosis, which can be used to determine

whether the sample comes from a normal distribution. Values of these

statistics outside the range of -2 to +2 indicate significant

departures from normality, which would tend to invalidate any

statistical test regarding the standard deviation. In this case, the

standardized skewness value is within the range expected for data from

a normal distribution. The standardized kurtosis value is within the

range expected for data from a normal distribution.

The StatAdvisor

---------------

This option performs a frequency tabulation by dividing the range

of # PERSONAS POR HOGAR into equal width intervals and counting the

number of data values in each interval. The frequencies show the

number of data values in each interval, while the relative frequencies

show the proportions in each interval. You can change the definition

of the intervals by pressing the alternate mouse button and selecting

Pane Options. You can see the results of the tabulation graphically

by selecting Frequency Histogram from the list of Graphical Options.
