Explanation / Answer
a) The explanation for the measures of central tendency for the star hotels based on the data provided in the question.
Mean - 61.07143, 82, 116.4762 - This is the average value of the price
Median - 64 85 116.5 - Reprsent the centre value of the price when arranged in ascending or descending order
Mode - 68 87 124 - The price which occur for maximum number of hotels in each bucket
Standard Deviation 19.1278 24.49888 32.56606 - Standard deviation gives an idea of the spreadness of the data. The data present shows that the data the four star hotels shows the maxium variation of prices across hotels
Sample Variance 365.8728 600.1951 1060.548 - Shows the same thing as Standard deviation. Squared value of Standard deviation is Variance
Range 87 124 137 - Difference between maximum and minimum price
Minimum 23 28 63 - Minimum price in each category
Maximum 110 152 200 - Maximum price in each category
Sum 2565 3444 4892 - Sumof the prices of hotels in each category
Count 42 42 42 - Number of hotels in each category
First Quartile 49 63 96 - This is the 25th Percentile value when arranged in ascending order
Third Quartile 71 94 135 - This is the 75th Percentile value when arranged in ascending order
Interquartile Range 22 31 39 - Difference between the third and first quartile values
Correlation Coeffient - This value gives how strongly the data of the two category related to each other. If the correlation coefficinet is greater than 80%, this shows that the prices on the two category are highly related
