Answer
Step 1: Add the scores = 30 + 91 + 0 + 64 + 42 + 80 + 30 + 5 + 117 + 71 = 530. Step 2: Divide by the number of observations: 530 ÷ 10 = 53. Answer: Mean = 53.
बल्लेबाज ए ने 10 मैचों में 30, 91, 0, 64, 42, 80, 30, 5, 117, 71 रन बनाए। माध्य ज्ञात कीजिए।
Answer
चरण 1: स्कोरs = 30 + 91 + 0 + 64 + 42 + 80 + 30 + 5 + 117 + 71 = 530. जोड़ें चरण 2: प्रेक्षणों की संख्या से भाग दें: 530 ÷ 10 = 53. उत्तर: मीn = 53.
Batsman B scored 53, 46, 48, 50, 53, 53, 58, 60, 57, 52 in 10 matches. Find the median.
Answer
Step 1: Arrange in order: 46, 48, 50, 52, 53, 53, 53, 57, 58, 60. Step 2: There are 10 observations, so median is the mean of the 5th and 6th observations. Step 3: 5th = 53 and 6th = 53. Step 4: Media…
बल्लेबाज बी ने 10 मैचों में 53, 46, 48, 50, 53, 53, 58, 60, 57, 52 रन बनाए। माध्यिका ज्ञात कीजिए।

Same mean and median show the centre of the data, but they do not show how far the values are spread out. Batsman A has scores from 0 to 117, so the spread is large. Batsman B has scores from 46 to 60…
दो डेटा सेटों का माध्य और माध्यिका समान क्यों हो सकता है लेकिन प्रसार अलग-अलग क्यों हो सकता है? दो बल्लेबाजों के स्कोर को एक उदाहरण के रूप में उपयोग करें।
Answer
माध्य और माध्यिका दोनों ही डेटा के केंद्र को दर्शाते हैं, लेकिन वे यह नहीं बताते कि मान कितने दूर तक फैले हुए हैं। बल्लेबाज ए के स्कोर 0 से 117 तक हैं, इसलिए फैलाव अधिक है। बल्लेबाज बी के स्कोर 46 से …
