QUESTION 1 You observed distance between two points by a total station during 1 day, starting from 8 am until 2 pm, taking individual measurements every 30 min. Within a period of measurements, the atmospheric temperature increased from 10°C (at 8 am) to 35°C (at 2 pm). What type of errors will affect your measurements? O random random and systematic O systematic decrease of measured distance due to atmospheric temperature change O all types of errors affect any type of measurements QUESTION 2 The outlier detection is applied to: O remove systematic errors O select outliers and inliers O detect gross errors O select only the most precise measurements for the least-square adjustment QUESTION 3 What is the best selection criterion (among four given options) for the outlier detection? (sigma is the standard deviation) 1xsigma 2xsigma O4xsigma O 1/2xsigma QUESTION 4 The true error is defined as: O most probable value - measured value O measured value - most probable value O true measurement - mean value O none of the above is true QUESTION 5 The normal distribution was introduced by: O Gauss Lagrange O Newton O Darwin
