Use analyze / descriptive statistics / frequencies to obtain a frequency distribution. To understand how many parking places are necessary, compute what percentage of visitorsĬomes by car and what percentage comes by bicycle. Variable level of measurement allowed to calculate means?Ģ. Of which variables are you allowed to calculate means? Determine the level of measurement of each variable in the dataset. Which critical t-value should you use? 1, Z = (5-2)/3=Ĭalculate the 95% confidence interval for the mean distance between home and shopping centre.Īssume that the sample contains 2000 observations. Calculate the z-value that will help you to compute this percentage. You want to know which percentage of visitors lives within the distance of 5 km from the shoppingĬentre. The variable ‘distanceīetween home and shopping centre’ is normally distributed, has a mean of 2 km and a We have a data sample with people visiting a shopping centre. Subtract the mean and divide the result by the standard deviation Subtract the standard deviation and divide the result by the meanī. To standardize a variable (bring its distribution to a standard normal distribution) oneĪ.

A mean of 1 and a standard deviation of 0 A mean of 0 and a standard deviation of 1ī. What percentage of the values falls within the interval ? A Take a normally distributed variable with a mean Mu and a standard deviation Delta.
