Question

Big Orange Trucking is designing an information system for use in “in-cab” communications. It must summarize data from eight sites throughout a region to describe typical conditions. Compute an appropriate measure of central location for the variables wind direction, temperature, and pavement. (Note: Trace indicates slightly wet.)

Answer:

Wind direction [Mode] is South west

The [Mean] temperature is  $T = 91$

The  [Bimodal] pavement is  Dry Wet

Step-by-step explanation:

From the question the first question is to determine the wind direction

Generally from the wind direction would be the data with the highest frequency on the wind column i.e the mode of the data, this because this variable(wind direction ) is a nominal level type of level of measurement where the value assigned to the variable are for classification of the data (i.e telling what the data is all about )

So

The mode is South west

This means that the wind direction is South west

From the question the second question is to determine the temperature

Generally given that their are are no outlier that will skew the data we can obtain the temperature by calculating the mean for the temperature column

This is mathematically represented as

$T = \frac{89 + 86 + \cdots + 93 + 93}{8}$

          $T = 91$

From the question the first question is to determine the  pavement

Generally from the pavement would be the data with the highest frequency on the pavement i.e the mode of the data, this because this variable(pavement ) is a nominal level type of level of measurement where the value assigned to the variable are for classification of the data (i.e telling what the data is all about )

From the table we see that the pavement that the pavement column is bimodal

So the mode is Dry  Wet

This mean that the pavement is Dry Wet
