According to our information compiled (see attached excel file for mega stat), the measure of tendency that best represents the data set is the median because the variability of the data is less between mean and mode data set. In addition, the outlier is less between mean and mode.

VARIABLES MEAN MEDIAN MODE

Bedrooms 3.80 4.00 4.00

Size 2,223.81 2,200 2,100

Baths 2.081 2.00 2.00

According to our computation for measure of dispersion (see attached excel file for mega stat), we found out that there are low and high outliers that existed on one of the variable. Under the size of the house column, the low outlier shows 1 deviation and 3 deviations on high outlier. It means that there is variability in the measurement or possibly, an error on the data gathered.

VARIABLES STANDARD DEVIATION SAMPLE VARIANCE SKEWNESS COEFFICIENT OF VARIATION

Bedrooms 1.50 2.26 .66 39.54%

Size 248.66 61,831.50 .32 11.18%

Baths .393 .154 .794 18.89%

The appropriate bivariate chart to use in this scenario is the scatter gram which is defined as a two-dimensional plot, with one variable’s values plotted along the horizontal axis and the other along the vertical
