A psychologist applies a general knowledge exam to enter the baccalaureate, which consists of 270 questions to 70 candidates to enter that level with a concentration in criminal justice. With the results of the tests presented later, considering that they represent the number of questions answered correctly for each candidate, calculate the measures of central tendency for non-grouped data (mean, mode, and median) and for the data grouped first. Developing a frequency distribution table with 6 intervals and plotting the histogram, the frequency polygon and the warhead, calculate for these grouped data: the mean, the mode and the median. 65 99 125 163 174 186 208 65 100 128 164 175 188 209 72 105 137 164 175 190 210 73 109 140 167 175 192 211 75 111 147 168 179 192 217 85 111 147 168 179 193 228 85 115 151 169 182 197 231 85 120 158 169 183 200 237 93 121 160 170 185 203 246 99 124 160 172 185 205 255
