Question
Find the median and mean of the data set below:28, comma, 49, comma, 23, comma, 7, comma, 12, comma, 19, comma, 928,49,23,7,12,19,9
Solution 1
Para encontrar la mediana y la media del conjunto de datos proporcionado, sigamos estos pasos:
-
Ordenar los datos en orden ascendente: Los datos son: 28, 49, 23, 7, 12, 19, 9. Ordenándolos: 7, 9, 12, 19, 23, 28, 49.
-
Encontrar la mediana: La mediana es el valor que se encuentra en el medio del conjunto de datos ordenado. Como hay 7 números, la mediana será el cuarto número. Mediana = 19.
-
Calcular la media: La media se calcula sumando todos los valores y dividiendo por el número total de valores. Suma de los valores = 7 + 9 + 12 + 19 + 23 + 28 + 49 = 147. Número total de valores = 7. Media = 147 / 7 = 21.
Por lo tanto, la mediana es 19 y la media es 21.
Solution 2
Sure, let's start with arranging the data set in ascending order: 7, 9, 12, 19, 23, 28, 49.
-
To find the median, we need to find the middle number. Since there are 7 numbers, the median is the 4th number, which is 19.
-
To find the mean, we add up all the numbers and then divide by the count of numbers.
(7 + 9 + 12 + 19 + 23 + 28 + 49) / 7 = 147 / 7 = 21.
So, the median of the data set is 19 and the mean is 21.
