implement a student class
Determine the final scores, letter grades, and rankings of all
students in a course.
All records of the course will be stored in an input file, and a
record of each student will include the first name, id, five quiz
scores, two exam scores, and one final exam score.
For this project, you will develop a program named cpp to determine the final scores, letter grades, and rankings of all students in a course. All...

Unit 6 Lesson 3 Classwork (Adapted from Math Vision Project) Data Distribution A lot of information can be obtained from looking at data plots and their distributions. It is important when describing data that we use context to communicate the shape, center, and spread. Shape and spread: Modes: uniform (evenly spread- no obvious mode), unimodal (one main peak), bimodal (two main peaks), or multimodal (multiple locations where the data is relatively higher than others). Skewed distribution: when most data is...
