Dr. Crumpler was practicing medicine in Boston after the Civil War. At the end of the Civil War wanted to go to Richmond, Virginia as a “proper field for real missionary work” caring for those who used to be enslaved. What do you think she meant by the quote?

Today we celebrate the life of Rebecca Lee Crumpler (1831-1895). She is best remembered as the first African-American woman physician in the United States.

Born Rebecca Davis in Delaware on February 8, 1831, she grew up in Pennsylvania, where her aunt provided care for the ill.

A bright girl, Rebecca attended a prestigious private school, the West-Newton English and Classical School in Massachusetts, as a "special student." In 1852, she moved to Charlestown, Massachusetts, and worked as a nurse. In 1860, she took the bold step of applying to medical school and was accepted into the New England Female Medical College.

The New England Female Medical College was based in Boston and attached to the New England Hospital for Women and Children. It was founded by Drs. Israel Tisdale Talbot and Samuel Gregory in 1848 and accepted its first class, of 12 women, in 1850. From its inception, many male physicians derided the institution, complaining that women lacked the physical strength to practice medicine; others insisted that not only were women incapable of mastering a medical curriculum and that many of the topics taught were inappropriate for their "sensitive and delicate nature."

Fortunately, Drs. Talbot and Gregory ignored such false claims and organized a school that required "a good English education," a "thesis on some medical subject," and a set of courses on the theory and practice of medicine, materia medica, chemistry and therapeutics, anatomy, medical jurisprudence, obstetrics and diseases of women and children, and physiology and hygiene. The coursework was 17 weeks in length (30 or more hours per week) during the first year of instruction. Following this was a two-year preceptorship, or apprenticeship, under an established physician's supervision.

In 1864, Rebecca became the New England Female Medical College's only African-American graduate (the school closed its doors in 1873.) A few statistics help put her remarkable achievement in perspective. In 1860, there were only 300 women out of 54,543 physicians in the United States and none of them were African-American. Some historians have wondered if Rebecca even knew of her status as "the first" given that for many decades in the 20th century that credit was awarded to Dr. Rebecca Cole, an African-American woman who received her medical degree from the Woman's Medical College of Pennsylvania in 1867. The first "historically black" medical school in the U.S., the Howard University College of Medicine, would not open until 1868. As late as 1920, there were only 65 African-American women doctors in the United States.

Around the time of her graduation, Rebecca married for the second time. (Her first marriage to Wyatt Lee, from 1852 to 1863, ended with his death in 1863.) In 1864, she married Arthur Crumpler. Rebecca began a medical practice in Boston.

Range

The range measures the spread of the dataset by calculating the difference between the largest and the smallest element. In your case, marks range from 6 to 10, so the range is 10-6=4.

How many students

The frequency tells you how many students got each mark. So, we know that 5 students got a mark of 6, 4 students got a mark of 7, 7 students got a mark of 8, 10 students got a mark of 9, 4 students got a mark of 10.

This implies that, in total, we have

students.

Mean

The mean is given by the sum of the marks, divided by the number of students. We already observed how many students got each mark, so the sum of all marks will be a weighted sum, where each mark counts once per student:

Now we divide this sum by the number of students to get

So, the average mark is about 8.
