Frequency:
Answer these questions:
Calculate the relative frequency of left-handed and right-handed people. Do your results agree with the statements from medical news site?
Think of a way to increase the frequency of each category. If you are to run a simulation of 1,000 trials, what object will you use? How will you design the simulation?
Handedness: Left-handed Right-handed Both
Number of people Relative: Left-handed - 200 Right-handed - 750 Both - 50
Frequency: Left-handed - 20% Right-handed - 75% Both - 5%
To calculate the relative frequency, we add up the total number of left-handed individuals (200) and divide it by the total number of people (1000) to get 20%. Similarly, for right-handed individuals, we divide 750 by 1000 to get 75%. These results do not necessarily need to agree with statements from a medical news site, as the sample size might be different.
To increase the frequency of each category in a simulation of 1,000 trials, we can use a spinner with three sections: one for left-handed, one for right-handed, and one for both. Each section would be proportionate to its relative frequency (20%, 75%, and 5% respectively). We could then spin the spinner 1,000 times and record the results to see if the relative frequencies approach the expected values.
