The outliers in the one-year audit program are by and large attributed to two factors: the position of the hearer ( whether the hearer is senior or freshly hired. and the figure of undertakings an hearer works on a specified period of clip. If an hearer is freshly hired. it is really likely that he/she will carry through an audit program for at least 6 to 8 months. A senior hearer normally finishes an audit program for at least 4-5 months. The strength of the outliers. nevertheless. besides depends on the ratio of senior to junior hearers.

If senior hearers outnumber junior/newly hired hearers. so the distribution is skewed to the left ; otherwise skewed to the right. If the distribution is skewed. so the norm is closer to either dress suits of the distribution. The figure of undertakings hearers undertake is besides a important factor in explicating the outliers. The mean figure of undertakings that an hearer accomplishes can be translated to a span of clip. This span of clip can be measured in existent footings by plotting the entire figure of undertakings on a graph with regard to clip.

The outliers of the graph are a contemplation of the outliers in the audit program ( note that the ratio of senior to freshly hired hearers is non included in this analysis – this is called factor isolation ) . 2 ) Evaluating Data based on Gender. Age. and Income Evaluating informations based merely in income will uncover a normal distribution of the samples. Because income is a uninterrupted variable. so it can be expressed in a chance denseness map. The deduction: if specific parametric quantities are established. income will uncover a level normal distribution.

Choosing clients in the age scope 18-25 will uncover a level normal distribution of holding a checking. nest eggs. and Cadmium histories for illustration. The standard divergence is 3 old ages. Gender is a categorical variable. can non be plotted in a PDF graph ( it can be plotted in a cumulative chance distribution graph ) . It has merely two categorizations: male and female. The deduction: distribution can non be expressed in existent footings. Probability replaces normal distribution in measuring the categorical character of gender. For illustration. one can reason that out of the 100 18 year-old males. merely 20 have look intoing histories ( 25 % of the sample ) .

Note that when plotted in a graph. merely two categorizations are in the X-axis ( with regard to look intoing. nest eggs. and Cadmium histories. Age is besides a categorical variable with besides the same deductions as that of age. 3 ) Response The ground why the distribution is non normal when compiled into a spreadsheet is because of the nature of the variables used. Note that chief variables used ( old ages of experience and hearer enfranchisement – certified vs. non-certified ) are categorical variables. Again. when a statistician uses this types of variables. it is plotted in a CDF. non in a PDF.

Normal distribution is non shown in a CDF. What is shown in a CDF is the ratio of chances between the classs of specified variables. Suppose there are 5 certified and 5 non-certified hearers. and the several chances are 75 % and 25 % . If plotted in an ordinary graph. it distribution will ever be skewed to the right. The variables involved here are discontinuous variables. These variables can non be expressed in ratio or interval footings ( unlike the variables temperature. income. and weight ) .
