Can my grade go up by 14 points in one test?

It depends on how much percent the test is worth and everything you might be missing but more than likely no you'd have to do really well on the test and a few assignments . There's a way you can calculate your grade with whatever you might be missing and the grade you're trying to get in the class.

you'd have to divide your grade in each category by 100 then multiple it by the percentage and add everything together for example:

Homework is 20% of a grade . I have a 90 in the homework category . 90/100 times 20 which will give me 18 then put the 18 over 20. 18/20

Projects are 30% of a grade. You have a 50 out of 80 do 50/80x30. which is 18.75 out of 30.

Final is 50% lets say you get a perfect score on the final meaning you get 50 points.

add 18+18.75+50= 86.75

add 20+30+50=100

you'd make a 86.75 in the class so a B. hopefully this helps . So if you need 14 points you should go to your assignments/tests and it should say how much there worth.

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
