Question

An article gave data on various characteristics of subdivisions that could be used in deciding whether to provide electrical power using overhead lines or underground lines. Here are the values of the variable x- total length of streets within a subdivision: 280 5320 4390 2100 1240 3060 4670 050 360 3330 3380340 1000 960 320 530 3350 540 3870 1250 2400 60 1120 2120 450 2250 2320 2400 150 5700 5220 500 1850 2460 5750 800 2730 1670 100 5770 3150 1990 10 240 396 1419 2109 How would you describe the shape of the histogram? (Select all that apply) A typical data value is somewhere in the low 2000's. 0 The display has a negative skew The display has a positive skew The display is symmetric @Atypical data value is somewhere in the high 300s.

Explanation / Answer

The histogram is used to find the distribution of the data or the to know the shape of the data.

I.e. Data is positively /negative skewed or symmetric.

Positively skewed means a decrease in values.

Negatively skewed means increase in values

and symmetric means the same shape either side of the middle of histogram.

From the above histogram we can say that the display is positively skewed.
