Subject Code: CP2403 Internal Code: 1AIAID

Computer Science Assessment Answer

TASK: Scenario 1 The California Cooperative Oceanic Fisheries Investigations (CalCOFI) was formed in 1949 to study the ecological aspects of the sardine population collapse off California. CalCOFI conducts quarterly cruises off southern & central California, collecting a suite of hydrographic and biological data on station and underway. The CalCOFI data set represents the longest (1949-present) and most complete (more than 50,000 sampling stations) time series of oceanographic in the world. The physical, chemical, and biological data collected at regular time and space intervals quickly became valuable for documenting climatic cycles in the California Current and a range of biological responses to them. Data collected at depths down to 500 m include: temperature, salinity, oxygen, phosphate, silicate, nitrate and nitrite, chlorophyll, transmissometer, PAR and C14 primary productivity. CP2403 You are provided with the following:- 1. bottle.csv 2. CalCOFI Database Tables Description - Bottle Table Using the dataset and codebook provided, select 1. a categorical variable and quantitative variable from the dataset to perform ANOVA analysis. (if you want, convert one quantitative variable into a categorical variable and then perform ANOVA analysis). What is conclusion can you draw from the ANOVA analysis? CP2403 2. 2 categorical variables from the dataset to perform Chi-Squared Test. (if you want, convert one or more quantitative variable into categorical variables and then perform Chi-Squared Test). What is conclusion can you draw from the Chi-Squared Test? 3. 3 or more variables from the dataset to perform multiple regression. What is conclusion can you draw from the regression analysis? CP2403 Scenario 2 You are provided with the Iowa Lottery Weekly Sales by Game Type Dataset. Select one game type and perform time series analysis (ARIMA). What conclusion can you draw from the ARIM analysis? CP2403
