HI!
How can I show how are the employees (field cod_empl) out of the normal distribution of the curve?
Is it possible thay if no year is selected show the curves of all years?
Are the expressions ok or there is something wrong?
Please see my attached file
Thanks in advance!!
>>How can I show how are the employees (field cod_empl) out of the normal distribution of the curve?
Define the extremes. Do you mean more than 2 standard deviations from the mean? Or do you mean by fractiles?
>>Is it possible thay if no year is selected show the curves of all years?
That's that way Qlik behaves out of the box.
Hi!
In my first question, i mean standar deviations from te mean, so when a value from the list box assig is selected, a table box or a straight table show who are outside the normal distribution and their values.
In my second question I was referring to that if no year is selected, a bell curve for each year is shown at the same time. In my chart example, if no year is selected, only one bell curve is show
My thrid question, I mean that if, for example, t2 is selected, the bell curve has a strange shape since it does not reach the axis of the dimensions completely.
Thanks for your interest and for your time.
>>In my second question I was referring to that if no year is selected, a bell curve for each year is shown at the same time. In my chart example, if no year is selected, only one bell curve is show
Then add Year as a dimension to the chart

Real data may not be normally distributed, and if you have a small data set, you may not have enough data points to get a bell shape.
A normal distribution is a common pattern for the general behaviour of attributes in a population, but any real world sample can only approximate the normal distribution, or it may not be normal at all. For example waiting times in a queue are not usually normally distributed.
Thanks for sharing your knowledge, really didactic!!
Ok, based in yoru explanation, i need to show the persons in the " remaining items outside that std deviation range are then considered outliers".(positive and negative)
Abusing a little of your kindness, when you refer to fractiles, do you mean the value that I define in the list box Desv?
Really apreciate your interest in helping me.
