IB Math Studies Test Taking Strategies
Studying for the test. n n Practice every test problem ever given to you! Use the formula packet when practicing to familiarize yourself with where everything is located!
Studying for the test. n n Financial Math! For the "we buy “, "we sell" problem remember to use the rate for what the bank is doing. Be careful of conversions! l Use: King Henry Died _ Drinking Chocolate Milk n Know what is contained in each of the number sets: reals, rationals, irrationals, integers and natural numbers.
Studying for the test. n n For chi-squared, if your value of chi-squared is greater than the CRITICAL VALUE you reject the null hypothesis. For p-values, the opposite is true. If your p-value is less than the SIGNIFICANCE LEVEL, you reject the null hypothesis.
Studying for the test. n n Remember that a linear regression always goes through the mean point The derivative is = 0 at a maximum or minimum!!!
CALCULATOR DIRECTIONS n n When using substitution into a formula, use ( ) around numerators/denominators Make sure you can find the intersection of two graphs with the calculator l n CALC (2 nd TRACE option 5) Make sure you know how to find maxes and minimums using a calculator. l CALC (2 nd TRACE option 3 or 4)
CALCULATOR DIRECTIONS n Make sure you know how to use the calculator stat functions. l l STAT Edit STAT CALC n n n 1 -Var Stats for L 1 2 -Var Stats for L 1 and L 2 Lin. Reg for linear regression n Use linreg for r as well! n Know how to run the chi-squared test in the calculator. l l MATRIX Edit (put in table without totals) STAT TESTS X 2 - Test…
CALCULATOR DIRECTIONS n Normal Distribution functions! l DIST (2 nd VARS) l normalcdf(lower, upper, mean, sd) l l Use when given a % in the probelm: invnorm(% to the left & out of % form, mean, sd)
Before the test. Sleep well the night before. n Eat breakfast. n Eat lunch. n Be hydrated, but not so much that you float away. n
During the test. Your calculators have been cleaned out! n Make sure you are in degree mode. n Make sure your diagnostics are turned on. n
During the test. Start each problem on a new page. n In Paper 1, always write the full answer before rounding in the working box. n Looking at point values…low point values on Paper 2 items imply use of the calculator. n
During the test. If you don't know an equation/answer. . . make it up. Finish the problem using the made up equation. n Look at the problem: “Show that” means they want you to get that answer. And that answer will most likely be used in future parts. n
During the test. Graphing: label the axes! n Make sure you know what a cm is on our graph paper. n Use the appropriate scale given in the problem. n Make sure you “show your work” on the graphs if you get information from the graph. n
During the test. If you must draw a Venn Diagram remember to label the Universal Set! n Pace yourself! When you read the exam make a strategy for how you want to attack the problems. n
