Statistical survey

Write TRUE OR FALSE for each question:

1 Standard deviation is a measure of central location.
2. The most frequent observation in a data set is known as the mode.
3 The most passive method of data collection is observation.
4 Access time for secondary data is short.
5. The volume of liquid consumed by an athlete during a marathon is quantitative and discrete.
6 in linear regression and correlation, a Pearson's correlation coefficint of -0.92 indicate a strong and direct relationship between the independent and dependent variables.
7 in normal distribution, the area between z=0.2 and z=1.2 is 0.3056.
8. In a binomial experiment, if the probability of a successful outcome is p, then the probability of a failure outcome is 1.0+p

Result
