what is the right syntax for getting the median?

• import scipy

  value = [99,86,87,88,86,103,87,94,78,77,85,86]

  x = scipy.median(value)

  print(x)

• from numpy

  value = [99,86,87,88,86,103,87,94,78,77,85,86]

  x = numpy.median(value)

  print(x)

• import numpy

  value = [99,86,87,88,86,103,87,94,78,77,85,86]

  x = numpy.median(value)

  print(x)

• import sklearn

  value = [99,86,87,88,86,103,87,94,78,77,85,86]

  x = numpy.median(value)

  print(x)

what is the right syntax for getting the mean?

• import numpy

  speed = [99,86,87,88,111,86,103,87,94,78,77,85,86]

  x=numpy.mean(speed)

  print(x)

• import scikit

  speed = [99,86,87,88,111,86,103,87,94,78,77,85,86]

  x=scikit.mean(speed)

  print(x)

• import scipy

  speed = [99,86,87,88,111,86,103,87,94,78,77,85,86]

  x=scipy.mean(speed)

  print(x)

• from numpy

  speed = [99,86,87,88,111,86,103,87,94,78,77,85,86]

  x=numpy.mean(speed)

  print(x)

what is the right syntax in getting the mode?

• import numpy

  speed = [99,86,87,88,111,86,103,87,94,78,77,85,86]

  x=numpy.mode(speed)

  print(x)

• import scipy

  speed = [99,86,87,88,111,86,103,87,94,78,77,85,86]

  x=scipy.mode(speed)

  print(x)

• from scipy import stats

  speed = [99,86,87,88,111,86,103,87,94,78,77,85,86]

  x = stats.mode(speed)

  print(x)

• from scipy

  speed = [99,86,87,88,111,86,103,87,94,78,77,85,86]

  x = stats.mode(speed)

  print(x)

how do you calculate the mean?

• by adding all values then divide it to the number of numbers in the data set

• by adding all values then divide it by 13 in the data set

• by subtracting all values then get the square root the data set

• by finding the middle number then divide it by 2

how do you calculate the median with even numbers?

• by adding all values then divide it to the number of numbers in the data set

• by getting both middle numbers

• by getting the middle number

• by adding both values then divide it by 2

how do you get the mode?

• by looking for repetitive values in the dataset

• by looking for the middle value which has repetitive value

• by adding all the repetitive values then divide it

• by looking for the repetitive values and count how many it has been repeated

what are the libraries needed for mean, median and mode?

• scikit learn

  matplotlib

• scipy

  sckit

• scipy

  numpy

• numpy

  matplotlib
