By negatively influencing data collection, ____ can have a detrimental effect on analysis.
oksano4ka [1.4K]

By negatively influencing data collection, <u>bias</u> can have a detrimental effect on analysis.

In statistical analysis, bias occurs when the data collected is not a true representation of the group under study. Bias occurs due to various mistakes or errors that occur at the time of data collection and sampling.

If a particular data is negatively influenced, then this means that there will be a bias in the expected results. Such a case can be highly detrimental especially if the studies would be implemented for a human issue.

The bias produced by a negative influence will cause errors in the analysis of the data leading to an overall wrong result.

Write the function lettersOnly(s) that takes in a string called s, and returns a string containing only the alphabetic character
Phantasy [73]

Answer:

The program to this question as follows:

Program:

def lettersOnly(s): #defining method lettersOnly

   val="" #defining string variable that return value

   for i in s: #defining loop to calculate value

       if(i.isalpha()): #check condition that value is string

           val=val+ i #add value

   return val #return value

print(lettersOnly("data3base_ro1c3k5s")) #call method and print value

Output:

databaserocks

Explanation:

In the above python code, a method lettersOnly is declared that accepts a string variable  "s" in its parameter. Inside the method, a string variable "val", and loop is declared, in which the "val" variable holds method return value.

  • In the loop and if block is used that uses "isalpha" string method, which checks the check alphabetic character in the given value. if this is true it will calculate all value in "val" variable and return its value.    
  • At the last, the print method is used, which calls the lettersOnly method and prints its return value.
