Question

1. This variable, number of jobs, is considered what type of variable (.e. continuous, nominal)? Explain your answer. 2. Would this be considered descriptive, correlational, or experimental research? Explain your answer. The researcher has collected the following data (number of jobs over their lifetime) from a sample of participants: 1,0,3,1, 2, 4, 5, 1, 11, 4, 4, 6 3. Create a grouped frequency distribution with 4 intervals with each interval 3 wide (hint: don't forget to include 0). 4. Calculate the mean, median, and mode of the distribution. 5. Calculate the variance and the standard deviation of the distribution.

Please put out steps for these 5 for me?

Answer 1

So it discrete nominal variable. I) Number of jobs - Grominal value betwan Number of gols can take discrete values 1, 2, .. & can't take any O & 1. So et is not continuous. like 0, 1, 2,
