Detailed Description

Class which is given measurements and computes some statistical parameters.

This class will add data to a database and can compute averages or standard deviations when called. It can also return the number of measurements in the database or can clear all numbers.

Constructor & Destructor Documentation

StatTracker()

StatTracker::StatTracker

(

void

)

Initialize variables for future statistical calculations.

This constructor initializes any necessary varaibles for when the object of the class is instantiated.

Member Function Documentation

add_data() [1/3]

void StatTracker::add_data

(

float

new_float

)

Add a float-type number to the database.

This float data will be added to the running sum and sumSquared variables. as well as increment the counter for the number of data points in total.

Parameters

new_float

The new floating-point number to be added to the class.

add_data() [2/3]

void StatTracker::add_data

(

int32_t

new_int

)

Add a signed int-type number to the database.

This int data will be added to the running sum and sumSquared variables as well as increment the counter for the number of data points in total.

Parameters

new_int

The new signed integer to be added to the class.

add_data() [3/3]

void StatTracker::add_data

(

uint32_t

new_uint

)

Add an unsigned int-type number to the database.

This uint data will be added to the running sum and sumSquared variables as well as increment the counter for the number of data points in total.

Parameters

new_uint

The new unsigned integer to be added to the class.

average()

float StatTracker::average

(

void

)

Computes an average of all data.

Returns

The average of all measurements that have been added to database.

num_points()

uint32_t StatTracker::num_points

(

void

)

Counts and returns the total number of data points added to the data set.

Returns

The number of measurements that have been added to database.

std_dev()

float StatTracker::std_dev

(

void

)

Computes a standard deviation of all data.

This standard deviation is given by the formula in the assignment.

Returns

The standard deviation of all measurements that have been added to database.
