Python can be used to implement central of tendencies such as mean, median and mode using the statistic module

The program in Python, where comments are used to explain each line is as follows:

#This imports the statistics module

import statistics

#This defines the function that calculates the mode

def calcMode(myList):

#This prints the mode

print(statistics.multimode(myList))

#This defines the function that calculates the median

def calcMedian(myList):

#This prints the median

print(statistics.median(myList))

#The main method begins here

#This initializes the list

myList = []

#The following iteration gets input for the list

for i in range(10):

myList.append(int(input()))

#This calls the calcMode method

calcMode(myList)

#This calls the calcMedian method

calcMedian(myList)

Answer:

Sort data in a range or table

Excel for Microsoft 365 Excel for the web Excel 2021 Excel 2019 Excel 2016 Excel 2013 More...

Sorting data is an integral part of data analysis. You might want to arrange a list of names in alphabetical order, compile a list of product inventory levels from highest to lowest, or order rows by colors or icons. Sorting data helps you quickly visualize and understand your data better, organize and find the data that you want, and ultimately make more effective decisions.

You can sort data by text (A to Z or Z to A), numbers (smallest to largest or largest to smallest), and dates and times (oldest to newest and newest to oldest) in one or more columns. You can also sort by a custom list you create (such as Large, Medium, and Small) or by format, including cell color, font color, or icon set.

Notes:

To find the top or bottom values in a range of cells or table, such as the top 10 grades or the bottom 5 sales amounts, use AutoFilter or conditional formatting.

For more information, see Filter data in an Excel table or range, and Apply conditional formatting in Excel .

Sort text

Select a cell in the column you want to sort.

On the Data tab, in the Sort & Filter group, do one of the following:

To quick sort in ascending order, click A to Z command in Excel that sorts A to Z or smallest number to largest (Sort A to Z).

To quick sort in descending order, click Z to A command in Excel that sorts Z to A or largest number to smallest (Sort Z to A).

characters++; //else increment character count this assures that there is no spaces count

}

printf("The file story.txt has the following Statistics:\n"); //finally print the final statistics

Which line in the following program will cause a compiler error?

Viktor [21]

Answer:

The answer is "Option A".

Explanation:

In the given C++ Language program on line 8 compile-time error will occur, because in the code the conditional statement is used. In if block, we check two conditions together, which is the number variable value is greater than equal to 0 and check less than equal to 100.
In this condition statement, a AND operator is used that execute when both condition is true, but in the last condition, we do not define a variable name that, checks value. That's why the program will give an error on line 8.
