Right now, will concentrate on building a model that helps in the expectation of understudy's exhibition with various properties remembered for it. The center is to show the disappointment aftereffect of understudies in an assessment. 

Process

The objective estimation of evaluation is G3. This qualities can be binned and additionally named disappointment and achievement. In the event that G3 esteem is more prominent than or equivalent to 10, at that point the understudy finishes the assessment. 

Example

Consider the accompanying model wherein a code is executed to anticipate the exhibition if understudies −

Output

The above code creates the yield as demonstrated as follows 

The expectation is treated regarding just a single variable. Regarding one variable, the understudy execution forecast is as appeared beneath −
