Step 2:Subtract the smallest number in the set from the largest number in the set: 8.3 hr – 2.7 hr = 5.6 hr The range is 5.6 hr. That’s how to find a range! Another Example of How to Find a Range Problem: You take 7 statistics tests over the course of a semester. You score...
How to Work With Probability and Statistics, Grades 6-8
Probability and Statistics>Sampling> What is a Sample? In statistics, you’ll be working with samples — a part of apopulation. For example, if you want to find out how much the average American earns, you aren’t going to want to survey everyone in the population (over 300 million peop...

Probability is the measure of the possibility that a given event will occur. Cumulative probability is the measure of the chance that two or more events will happen. Usually, this consists of events in a sequence, such as flipping "heads" twice in a row
Many statistical inference problems require us to find the number ofdegrees of freedom. The number of degrees of freedom selects a singleprobability distributionfrom among infinitely many. This step is an often overlooked but crucial detail in both the calculation of confidence intervalsand the ...
Click on the resulting cell, we will see the formula for the t-test in the formula bar. =T.TEST(C5:C13,D5:D13,2,2) Note:The t-test determines the likelihood that the difference in the two values is due to randomness. It is common practice to declare that if the probability is ...
Conditional probability is a term in probability and statistics that means one event depends upon another. For example, you might be asked to find the probability of getting a traffic ticket if you speed in a school zone, or find that an answer to a surv
Formula for the probability of A and B (dependentevents): p(A and B) = p(A) * p(B|A) The formula is a little more complicated if your events are dependent, that is if the probability of one event effects another. In order to figure these probabilities out, you must find p(B|A...
