Review the attached excerpt on coding Frequency Distribution routines.

Work through the examples and internal functions to manipulate internal Dictionaries to represent grades from a Computer Science class. From there, complete the following steps to implement code and show your output:

$1)$ Implement the frequencyTable function and show the output for the following frequency table:

frequencyTable$([3,1,1,5,3,1,2,2,3,5,3,5,4,4,6,7,6,7,5,7,8,3,8,2,3,4,1,5,6,7])$

Did you notice a discrepancy with the book excerpt?

$2)$ Implement the histogram generator as described in section $4\mathrm{.}6\mathrm{.}3$

frequencyChart$\{[3,3,5,7,1,2,5,2,3,4,6,3,4,6,3,4,5,6,6,]\}$

$3)$ Follow the instructions in section $4\mathrm{.}7$ to handle Standard Deviation. This includes covering the data lists in Session $4\mathrm{.}17-$ show your output.

Update $*$

From class we reviewed the basic requirements for HW #$3.$

It will make sense to code everything one module at a time to make sure that you are picking up on the method and intent. Here are the methods that I had in my demo code:

Mode

FrequencyTable

FrequencyTableAlt

FrequencyChart

StdDev

Assuming that you code one module at a time $($with prerequisites $-$ i$.$e$.,$ mode & StdDev$),$ here are the data sets that I need to see for the grading of your output:

A$)$ Print out FrequencyTable $-$ with mean score and Standard Deviation

# frequencyTable$([3,1,1,5,3,1,2,2,3,5,3,5,4,4,6,7,6,7,5,7,8,3,8,2,3,4,1,5,6,7])$

B$)$ Print out FrequencyTableALT $-$ with mean score & Standard Deviation

# frequencyTableAlt$([3,1,1,5,3,1,2,2,3,5,3,5,4,4,6,7,6,7,5,7,8,3,8,2,3,4,1,5,6,7])$

C$)$ Print out the GUI for FrequencyChart

# frequencyChart$([3,3,5,7,1,2,5,2,3,4,6,3,4,6,3,4,5,6,6])$

D$)$ Print out the GUI for FrequencyChart $-$ with a new set of grades.

# frequencyChart$([80,75,55,75,93,72,85,92,93,64,86,83,94,86,73,54,75,96,86])$
