With the scatter diagram, the regional sales manager of American Toys, Inc. can see that the stores where weekly hours of sales clerks are high, the sales are also high. However, the data also shows some outliers as we can see that store 3 with 96 hours has a sales figure of $19200 but even with increased hours of 102 by store 4, their sales are lesser valuing at $10211. The same can also be seen for stores 8 and 11. This means that there may be other factors that need to be considered before a generalization of the trend is made. However, the larger trend of the data reveals a positive relationship between the sales clerk’s work hours and the value of sales. The sales manager, if increased the work hours of sales clerk staff could get increased sales value as well.
